Motokosa engine stalls after heating. Features of diagnosis

Why does a trimmer for grass stall at idle

If the lawn mower stops when pressing the gas, then the prerequisites may be subsequent.

• The more increased option is a carburetor adjustment failure that appears with significant load loads after a long.term inaction of the mechanism or when using it in languid criteria.
• The clogging of the fuel valve, which relieve it with a message, as a result of which gasoline according to the system begins to flow normally.
• The weakening and hanging of the cable in the carburetor. There may also be a stretch of the fuel hose right to its gap, caused by the action of a significant load.
• The clogging of the soundtress (revolutionary valve), as a result of which fuel does not enter the tank.

If the inconsistent is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. When the hose bursts or the cable stretches, the devices are replaced.

Why stalls the lawn mower: reasons and solutions

The reason why your tool abruptly stops working, namely the engine does not gain revolutions, breaks them off, or “stalls” in popularity, there may be more than one. Often this is to blame not only the engine itself, but also the adjacent systems, unit nodes, completely different details related to the preparation of the fuel-air mixture, its quality, transportation to the tool of the tool. Consider the most typical situations:

• He is not gaining momentum. The engine drive mechanics may be damaged or there were problems with the carburetor, but the main reason should be considered clogging of the air filter. To change the situation, it must be removed, cleaned, and if it is no longer subject to the latter, then change for a new one, promptly making an order on our website. Also, there will not be a turn of the braid for grass, if the cable from the carburetor constantly flies. disassemble the unit and firmly fix it, or buy a new one if cracks are found on the element, other types of deformations.
• At high speeds. The lid on the gas tank is clogged. it needs to be cleaned or new. often the reason is a sipped carb. We submit information on the correct adjustment of all screws in information articles. Check the quality of the fuel hose and change it to a new one if necessary.
• When heated. It occurs in moments when the fuel in the carburetor literally boils. It can also appear in the options if the carba damper is more rare, rotary type (not disk). The only option would be to replace the carburetor with a new. There is another option for a broken wire or ignition coil. In this case, change the element of the latter.
• Starts and stalls (immediately after launch). Solved or incorrectly adjusted carburetor is the main reason for this situation. Calm vibration will indicate an uneven supply of fuel, and competent adjustment of the node will help to correct the situation.

We hope you found the right answer to the question: why the lawn mower stalls, and all the proposed catalog details today, as always, are at your service. You need a piston trimmer for grass, a new carburetor, or the elements accompanying the operation of these systems. you will find everything in the open spaces of the Benzo SIP store.

What could break

Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:

• the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
• the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• The ignition chain.

To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass.

Ways to eliminate breakdowns

Subsequent work is likely on the carburetor:

• cleaning and adjustment of the fuel supply valve;
• similar work with a valve producing redesigned gases and pairs (after burning fuel);
• replacement of the spring more weak on the entrance valve;
• restoration of the tension of the carburetor cable;
• replacement of the fuel leaks hose, verification and strengthening of a weakened connection;
• changing the rotor damper disk;.
• Change of faulty wire or ignition coil.

Immediately after the start

Smelting Motokos or a trimmer for the grass after starting is justified by subsequent reasons:

• impressive of previously adjusted valves;
• first the wrong settings of the valve mechanism;
• clogging with deposits of the fuel supply valve;
• the hose is worn or poorly annexed.

Due to the violated method of injection of a fuel, a lawn mower or a trimmer for grass is very vibrated in work.

Asseting device and common malfunctions

The easiest way to give the lawn mower for repairs, allocating a certain amount of funds from the family budget, operational and high.quality repair with your own hands is no less simple and convenient to understand the design of the lawn mower and fix all the problems.

The massive and piece manufacture of trimmers is based on the use of generally accepted technology, the typical design scheme consists of certain elements and parts, it is important to know them when carrying out independent repair work:

• top part. The basis of the entire structure, where all important elements are collected, such as the starter, carburetor and the engine of the lawn mower;
• middle part. Hollow rod, inside it is a cable connecting the engine and gearbox, which sets the cutting fishing line for the trimmer. In this part there are mounts for the distribution of weight of the entire structure and a belt for fixing a trimmer for grass on a belt of a person using a trimmer for grass for its intended purpose;
• Bottom part. It has a gearbox and cutting elements that are hidden under a practical casing, which protects the user. The casing provides an increased level of safety, preventing large fractions of garbage, pebbles and glass in a person while working with a gas station.

The most common and often encountered, subject to independent correction of the breakdown of the unit can be called the following problems:

• engine malfunction, due to which the lawn mower is not started and does not work;
• enhanced vibration of the bar motorcosa, which complicates its targeted use;
• increased overheating of the gearbox, its accelerated heating during operation;
• slow and weak functioning of the cutting fishing line at insufficient speeds;
• the clogging of the starter grill causing the engine overheating and its refusal to work;
• rapid and frequent clogging of the carburetor due to the use of poor.quality fuel;
• clogging of the air filter in case of non.compliance with measures to care for the device.

All these problems can lead to the fact that the device will lose its ability to work before ordering the necessary spare parts for non.bosomeds should be carried out by a visual inspection and diagnosis of the device.

Special attention is required by individual spare parts and assemblies of the device, to verify them, you will not have to turn to a professional master, a complex of diagnostic measures will help to identify a consequence of the occurrence of a loss of performance.

The lawn mower stalls

When purchasing a lawn mower, you need to be prepared for the fact that, as in all other similar tools, it may also have breakdowns that will require repairs.

However, do not immediately run to the service center and pay a lot of money to the masters who convince you of a serious malfunction in the device.

The lawn mower stalls at high speeds

Perhaps the most common complaint related to gasoline trimmers sounds like this: “The lawn mower stalls”.

Of course, the reason for this may be a rather serious malfunction. However, most often the situation is much simpler than it seems at first glance.

To cope with such a problem, first of all, try to deal with its causes on your own, because, having found out the reason, it is much easier to fight the problem, and sometimes it is even self.destructive.

In fact, the reasons are when the lawn mower stalls at high speeds, there are quite a lot of these reasons.

Another, this is the presence of malfunctions in the power system.

In this case, the lawn mower will stall at idle. The problems with the power system may lead to a drainage or incorrect carburetor adjustment.

Vibrations that take place in the process of operation of the lawn mower can lead to a reservoir.

Incorrect adjustment of the lawn mower can be fixed by simply adjusting it in accordance with the requirements specified in the operating instructions.

In addition, sometimes gasoline trimmers for grass can stall due to the fact that the valve located in the gas tank lid just clogged or sticks.

To find out, try using a braid by loosening the gas tank cover.

If in this mode the device works properly, clean the valve.

over, the lawn mower can stall due to poor fuel flow into the carburetor

Why then the device starts up, ask you?

The reason for this is that at first the fuel gradually falls into the carburetor and is enough for work with increased power.

However, then it is produced and at large speeds the engine begins to stall.

As for the carburetor, here the problem may also be that its body is too pulled.

The reason that the lawn mower stalls at high gas speeds may also be an air leak.

We are talking about the possible presence of a place through which air can pass during the heating process of the engine.

Among other things, do not forget to check the fuel intake hose. The problem may be that it is weak or cracked at all.

These are the main reasons why the gas mowl can stall.

The lawn mower stall when you press the gas, how to eliminate the breakdown

The reasons why the lawn mower stalls is a huge number, we offer the most common of them, and we hope that you will find your own, and, of course, eliminate it. So, one of the situations is to clog the air damper, then the hole behind which the fuel is sprayed. If something got into it, then it can most often be quickly and easy to remove. This is the simplest reason, like a clogged filter. It needs to be washed in the solvent, and then get it well with compressed air. If it is not subject to repair, then order a new one in spare parts from the Kosikos store.

Similarly, when you press the gas, the tool stalls because the drive has clogged. The following option is possible: the fuel does not come in full, so you need to check or replace the fuel filter. To other possible reasons, the stalled motorcycles, when you give gas, should be attributed:

To all these reasons for which the mechanism stalls when adding gas, we will add several useful recommendations for the treatment of a motorcycle. First of all, before starting working with any equipment, you need to read the instructions. In this case, an important role is played by the consistency of gasoline and oil, correctly prepared by you, and also not to overheat the unit, and not leave gasoline for the winter when you simply will not use the machine.

In the full work of any tool, an important role is played by the coordinated work of all its components. And if in one it is a fishing line for a trimmer for motorcycles, then in the other a piston or carburetor. Motokos owners who want to use their tools at full power, you need to understand that the load on which the capacity of the machine is not designed may simply break the entire mechanism or its individual parts. Therefore, only competent and moderate operation involves the long.term effective work of any benchmate tool.

The trimmer stalls for grass at idle. the causes and their solutions

To common situations why a trimmer for grass or a lawn mower stalls, it should be attributed to its work at idle. Let’s immediately move on to the reasons:

• heating the gearbox and sleeping on the drum as a result of the fact that the gasoline solution is not prepared correctly. The required proportion is 1: 4;
• carburetor pollution;
• The throttle flashed;
• When opening the damper (if the experiment was carried out), the air flow makes a mixture of the “poor”;
• Ringing the carburetor;
• clogging of the air filter;

The insufficient amount of fuel that you need to work as a gas tool will entail a situation when at high speeds, with an increase. a trimmer for grass works and stalls in idle. In a situation with a carburetor. the device will stall for a cold launch and “on hot”

For any user, Motokosa. Professional and Amator, it is important to understand that any tool problem can depend on the petty flying of the part, the release of fastening or clogging, as well as on the global breakdown of the important part of the mechanism

Despite all kinds of problems, your device, nevertheless, needs such an obligatory component as knives for motorcycle, without which the exploitation of braids for grass is simply impossible!

A gasoline trimmer for grass is a useful tool for cleaning from unnecessary grass of house territories and large area lawns. The design of this technique is quite complicated, therefore, if the device breaks, there may be several reasons. The most likely factors that have caught a breakdown are usually described in the user guide. Knowing why a trimmer for grass stalls, you can try to independently eliminate the defect. The most common malfunctions provoking the motorcycle stops, and the ability to repair them with your own hands is in the material further.

Why is the lawn mower stall at idle

Why does the lawn mower stall when you press the gas: the prerequisites and their solutions. The lawn mower stalls (trimmer for grass):. On idle

Users have repeatedly ask about stopping the braids for the grass “on hot”, that is, when the mechanism started, worked a little, and then took it. and stopped, stalled. The reasons for this situation are the following:

• problems with the carburetor damper;
• Gasoline in a carbe can even boil;
• If the ignition is damaged, then the trimmer for the grass will also heat up and stall.

In each of the situations, check the details for strength, and if they have already outlined their own, order new ones from specialists. We will call one of the most popular situations: the lawn mower stalls at idle. This happens for reasons:

• The carburetor was diluted himself, or was illiterately adjusted;
• the carburetor is contaminated;
• The air filter is very contaminated;
• The use of inappropriate fuel can cause a reduction in the gearbox revolutions;
• At idle, your trimmer for grass can stall if the throttle closed;
• Air fell into the carba system;
• The lawn mower receives a missing portion of gasoline to work fully, and therefore stalls.

We are sure that you received the maximum of useful information, and found a way out of your individual situation through our technical councils. Any spare parts, like a starter, motorcycles, its components and accessories are located at the lowest value in the country. Hurry up!

Recently, a gasoline trimmer for grass has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized braid for grass allows you to quickly put a personal plot in order. However, sometimes it happens that the trimmer for the grass does not start hot and even on cold.

Often, when reducing the speed, the motor motorcycles stalls and does not support idle speed when re.starting. The main reasons for the occurrence of such a breakdown include pollution or the dumping of the carburetor, as well as clogging of the air filter.

In case of violation of the optimal settings of the carburetor, it is necessary to clean it and repeated adjustment. You can cope with clogging the air filter of a trimmer for grass by placing it for several hours in a solution with a conventional domestic detergent. If independent cleaning has not helped to cope with the blockage, it is better to purchase a new filter element in accordance with the operating manual.

After the measures, the user will not encounter a situation for a long time when a trimmer for grass stalls in idle and functions only when gas supplies.

A braid braid with a gasoline drive is a useful thing for owners of personal plots, lawns, and when a trimmer for grass suddenly stalls, the work on cleaning the territory stops from the grass. The device itself is a rather complex mechanism, so there are many different causes of its breakdowns.

• reducing the speed of the gearbox when heating it, which is a consequence of the use of inappropriate fuel mixture;
• clogging of the throttle;

• air entering the system;
• not enough fuel for the operation of the lawn mower.

If a carburetor is a problem place, then the technique will stop at the “cold” and with a “hot” launch.

The trimmer for the grass is not started due to the malfunction of the carburetor

One of the most difficult reasons for the impossibility of launching a lawn mower is a carburetor. This mechanism is responsible for the preparation and good supply of the fuel-air mixture to the cylinder. If the carburetor is clogged or adjusted incorrectly, then the lawn mower may not start or work unstable. Detailed instructions on how to adjust the carburetor on a benzocosa is described in this material.

If the adjustment does not help restore the stable operation of the tool engine, or the trimmer for the grass does not start at all, then the carburetor should be removed and repair it. The entire repair of the carburetor is that you need to disassemble it, clean all channels and constituent elements. If necessary, replace the failed details. membranes, filters, etc.P.

If the suspicions fell on the carburetor, then you should pay attention to the following types of malfunctions:

• Canals and nozzles clogged. special liquids can be used for cleaning, however, it is best to disassemble the mechanism with its thorough flushing. The reason for the clogging of the channels and jackets of the carburetor is the storage of a tool with fuel in the tank
• Wear of the carburetor gaskets. rubber seals contribute to the fact that the tightness of the mechanism is disturbed, as a result of which the serviceability of the functioning is violated
• Memory of carburetor membranes. they are responsible for downloading fuel to the device

To make sure the CPG malfunction, you should check the compression, which is described above.

Chips on the choice

Now let’s try to understand how to choose high.quality oil for a trimmer for grass working on gasoline

The main feature that is required to pay attention will be an alkaline number. The moment excludes the oxidation of the parts that have friction, and slows down their deformation as much as possible

The more this composition is used, the faster it loses alkalinity and becomes more oxidized. The optimal indicator of acidity (pH) is a value of at least 8-9 units.

The second important factor, which also has a serious impact on the operation of a gasoline trimmer for grass, is the viscosity of the oil. This characteristic determines the possibility of using the device at various temperatures. Summer grades of oils begin to thicken already with a minimum decrease in temperature.

The third moment, the importance of which should not be understated. the temperature of the flash. This indicator should not be less than 225 degrees

Otherwise, the composition will burn very quickly and the load will begin to increase on the piston group, which will determine its accelerated wear. In addition, oil for a 4-stroke engine is not suitable for a 2-stroke. Namely, the last type of motors is used in the vast majority of benzocosyles.

If we talk about manufacturers, you can make a small rating that will allow you to navigate in the compositions offered by various manufacturers. For example, STIHL offers high.quality synthetic and mineral oils that have already proven themselves as an excellent solution at any time of the year.

Shell Helix Ultra oil is considered very good. Experts note its high characteristics and excellent indicators of alkalinity and viscosity. In addition, the products of such brands as Oleo-Mac, Motul, Hammerflex, Echo are considered worthy

If we talk about the products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than foreign analogues, but it has high quality and good technical characteristics

When pressing gas

If the lawn mower stops when pressing the gas, then the prerequisites may be subsequent.

• The more increased option is a carburetor adjustment failure that appears with significant load loads after a long.term inaction of the mechanism or when using it in languid criteria.

If the problem is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. Когда лопается шланг или растягивается трос — выполняют замену данных комплектующих.

At high speeds

When a braid for grass stalls at high speeds, this is due to the following problems:

• clogging or clutching a valve located on the gas tank lid;
• The carburetor was diluted under the influence of vibrations arising during the operation of the mechanism;
• Circulation problems fuel mixture;
• atmospheric air
• The hose intended for fuel fuel cracked or slightly connected.

The carburetor is regulated by relying on the operational instruction to the trimmer. For configuration, it is often enough to weaken the tightening of its body. If there are problematic issues with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its production, the engine stalls at high speeds.

The trimmer for grass stalls. how to eliminate the problem

A gasoline trimmer for grass is a useful tool for cleaning from unnecessary grass of house territories and large area lawns. The design of this technique is quite complicated, therefore, if the device breaks, there may be several reasons. The most likely factors that have caught a breakdown are usually described in the user guide. Knowing why a trimmer for grass stalls, you can try to independently eliminate the defect. The most common malfunctions provoking the motorcycle stops, and the ability to repair them with your own hands is in the material further.

In order to most accurately determine the cause of the trimmer malfunction for grass of any brand (for example, echo) and find out the possibility of eliminating it, you need to install, when performing what action the device stalls. The engine can turn off both at idle and at high speeds, heated under load or immediately after starting and t.D.

If you stalled after gas supply

Owners of gasoline braids often mention that the lawn mower stalls when you press the gas. Usually such a breakdown occurs due to problems in the carburetor. A failure in his work can occur due to long-term storage, use in difficult conditions, significant overload of the motor. The symptom of such a breakdown will be vibrating movements of the device during operation.

On a note! Users familiar with the repair of a car carburetor can try to restore this important node of the trimmer for the grass on their own, using the instructions for operating. Otherwise, the correct decision will be to seek help from the service center representatives.

Sometimes a trimmer for grass stalls when you give gas because the fuel valve is clogged. This interferes with the supply of gasoline. To eliminate the problem, it is enough to loosen the valve. Thus, normal supply of carburetor fuel will be restored.

Another possible reason why the lawn mower stalls when gas is supplied is pollution of the soundtress (check valve). This detail prevents the appearance of a vacuum in a gas tank. If it is clogged, the air does not flow, which means that fuel does not go to the carburetor. To eliminate the problem, it is necessary to clean this element.

If it stalled at high speeds

If the carburetor stalls at high speeds, this means that in idle and small there are enough incoming fuel, and to work on high is not enough. Then it is necessary to check the serviceability of the following nodes of the trimmer for the grass.

• Fuel hose. its integrity could be violated as a result of cracking. In this case, you need to replace the part. Or maybe you just need to tighten the clamps.
• A filter network between a carburetor and a hose for supplying a gasoline mixture-it could clog. In this situation, it is necessary to clean the detail.
• The valve on the gas tank cover. he could stick or clog with garbage. Cleaning is also necessary.
• Carburetor. perhaps as a result of constant vibration, it was resolved. This is usually characteristic of cheap Chinese details. To eliminate the problem, it is necessary to set up according to the instructions. In some cases, it is enough to only weaken the tightening of the carburetor case. If the adjustment is not possible, it is necessary to install a new element.
• Additionally, check the air filter. Perhaps it will need to be washed and cleaned or replaced with a new one, as he could clog with dirt and particles of grass when tilted technology, when the user mowed in hard.to.reach places.

If you stalled during work idle

If the lawn mower stalls, working idle, there may be several factors reasons.

• First you need to check the prepared fuel solution, when it comes to a four-stroke trimmer working on a gasoline-oil mixture. There is a chance that it is made incorrectly. the proportions are not withstanded. Because of this, the gearbox is warming up, and the revolutions on the drum are lowering.
• Another probable cause is blockage of elements such as a throttle, air filter or carburetor. You need to clean the indicated details.
• Another possible factor is to resolve or incorrectly carried out carburetor adjustment. You need to adjust the setting according to the instructions.
• Observe this problem mono and when opening the air damper. In this situation, the lack of fuel for a trimmer for grass occurs through the fault of the air flow.

If the device does not have enough fuel, it works properly at high speeds or when they increase, but stalls at idle. If the root of the problem consists in the carburetor, the lawn mower will be disconnected both with cold startup and hot.

If you stalled after starting

If the technique starts and stalls immediately after starting, this indicates the wrong settings or deducting the device. As a result of this, the fuel enters the engine unevenly, which leads to significant vibration and disconnecting the trimmer for the grass. To fix the breakdown, it is necessary to reconfigure the device according to the user management.

Another probable problem is the blockage of the valve supplying the gasoline mixture. It must be cleaned.

On a note! If the trimmer for the grass starts, but immediately stalls, it may also mean that the fuel is moving to the carburetor with difficulty. Weakening the valve will help to eliminate the problem. this will provide uniform and free circulation of fuel in the device.

Another possible reason is the damaged fuel intake hose. Air can penetrate through cracks and holes into the system. To solve the problem, you need to increase the engine speed in order to get rid of air bubbles that have penetrated the device.

If you stalled when opening the damper

If the technique works properly at idle, but stalls when opening an air damper, this reports about the penetration of air into the system through cracks in the fuel supply hose or damaged oil seals. To fix the breakdown and establish the work of the tool without driving air from the atmosphere, it is necessary to replace damaged parts.

Preventive measures and operating rules

So that the lawn mower does not work and does not stall when starting, it must be correctly stored and operated. Compliance with the following simple recommendations will forget about problems.

• When begging the grass, you need to monitor the state of the cooling system. It is also necessary to regularly clean the channels in the case and starter’s ribs.
• To clean the tool, you should use kerosene, solvent, or other washing tools.
• You can not clean a hot tool. it must cool before washing.
• It is important to observe the recommended working mode. this will avoid overheating of the engine.
• If a braid for grass is not used over the next thirty days, the fuel must be drained, otherwise it will fall into heavy components that can score the channels of the carburetor.
• After the fuel is merged, the trimmer for the grass should work at idle for some time until it turns off. This will allow you to completely get rid of the rest inside the working mixture.

To store the tool in cold weather, you need:

• completely drain the fuel;
• disassemble the lawn mower, wash and clean all available components;

• inspect the condition of the parts, eliminate all defects that can be corrected;
• pour the required amount of oil into the gearbox;
• Clean the air filter;
• perform partial disassembly of the engine, wash all moving parts, blow and lubricate thoroughly;
• To lubricate the piston, unscrew the candle, then raise the piston to the upper dead point by the starter, pour a small amount of oil into the hole for the candle and do the crankshaft several times.

Important! If there is no way to store a trimmer for grass in a warm dry room, you must first wrap the motor with an embarrassed rag.

Only by observing these rules, you can be sure that the lawn mower will work properly and will not stall for a number of seasons.

As you can see, stopping the work of a trimmer for grass can be caused by many reasons. Most of them can be fixed independently using the user instructions. In cases where there is no self.confidence, the equipment is recommended to be attributed to repairs. It is worth remembering that incorrect actions can cause even greater harm to the trimmer. As a result, the repair of Motokos will cost a much larger amount than it would be initially, and in the worst case, it may be necessary to buy a new unit.

Carburetor adjustment and configuration

The maximum and minimum engine speeds, even idle is regulated by the carburetor. The stable operation of the lawn mower depends on the amount of fuel mixture and air. The lawn mower is not started with disturbed adjustment of the carburetor. The procedure for setting up the device for supplying fuel at low speeds (L), high speeds (H) and idle (T) is regulated by the same vints:

• The chainsaw should work for at least 10 minutes, since the adjustment is carried out in hot.
• The screw n is flooded smoothly to maximum speed, then turning on ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
• The idle stroke is regulated by the screw T, ensuring that the braid for the grass does not rotate.
• The screw l is regulated, first opening the throttle as much as possible, and then smoothly reducing the speed to stable minimum.

After adjustment, a proper carburetor with cleaned filters should ensure the operation of the engine. In the event of a malfunction of the carburetor, after its repair, it will again need to configure the supply system before starting the lawn mower.

Rare breakdowns that prevent the operation of the lawn mower can be:

The most important malfunction, the elimination of which is associated with the replacement of the engine may be the failure of the piston group of the engine. Why does a lawn mower or a lawn mower stall when you press gas, at idle, when heated and other causes of non.taxes of a gasoline trimmer for grass. The cost of repair will cost about 70% of the cost of the product. The lawn mower stalls or a trimmer for STIHL grass stalls when why Chinese. To figure out the reasons why the lawn mower is not starting up will help

Need help, advice, Hy 30 is not started to hot.SS

If the fuel itself retreats, and then returns, it is likely that the pressure in the pipeline is to blame (sometimes excessive or sometimes insufficient), and this is apparently connected either with: a) with the temperature. Can fuel boil in a carburetor when the engine overheats during movement? What is the temperature after a long trip? B) or over time. Then maybe something was jammed somewhere. Not deadly, but still. For example, an air filter (dust, excess oil on it), draining in the cork of the tank, fuel filter, clamped fuel pipeline, etc. D.

Unscrew the spark plug, and if it is completely tanned or filled with fuel, then you need to be poor. And try the iridium candle. It works a little better with a problem engine, especially when overflow.

Why stall the engine of a trimmer for grass when recruiting

The most popular with summer residents, gardeners and gardeners trimmers for grass are equipped with two.stroke engines operating on gasoline. In recent years, part of the manufacturers have been promoting motorcycles and leaflets based on four.stroke engines in the market, but they have not yet gained the popularity that two.stroke. They are more difficult in the device, more demanding on the mode of operation, purity of fuel, oil quality. Also, four.stroke engines are more in weight and more slowly gaining momentum.

During the operation of trimmers on the basis of two.stroke engines, a number of characteristic malfunctions arise related to the features of the design of the engines. With all the perfection of the Husqvarna or Echo engines, even they occasionally “acting up”. The budget models of motorcycle assembled in China, problems arise more often. This is due to both the lower quality of materials and the assembly level. The most characteristic malfunction is a poor launch from a “hot” state and “subsidence” of revolutions at a slight load. But sometimes a trimmer for grass stalls with a sharp press on the throttle key. Why does this happen?

The reasons for the breakdown

For all the apparent simplicity, the lawn mower is a well.thought.out and balanced tool in which each part is in its place. If everything is regular, the engine from the cold state should start after the first starter jerk. Depending on the model, first you need to swing the fuel mixture by pressing the transparent button on the carburetor. In a number of modern fuel pumping models, it is not required.

You also need to transfer the lever on the carburetor to the extreme position to close the air damper. In some models of Husqvarna and other manufacturers, the shuttle of the damper is carried out by turning a special regulator. After that, you need to turn on the ignition on the handle and energetically pull the starter’s cord, while pressing the gas key to about half.

The engine should start after the first jerk, but can earn after 3. 4 movements. This cannot be considered a breakdown. it all depends on the production of the motor, the quality of the fuel mixture, temperature and humidity and other factors. Two.stroke engines have their own character, to find out why they are not launched from the first, but from the fourth time, it is difficult even for professional mechanics.

If the engine confidently launched and earned, but the trimmer for the grass stalls when pressing the gas, then you forgot to transfer the carburetor lever to the position of the open or partially open air damper. Usually. this is the movement of the lever down. It may happen that the most stable the lawn mower works with a not fully opened damper. If you have used the trimmer for more than one season, so it will be. When the lever of the damper is transferred to the extreme lower position, the fuel mixture can become too impoverished and the trimmer for the grass stalls when you give gas.

This feature is not considered a malfunction. you just need to check the work of the trimmer for grass in different modes and try to use the optimal one in work. But there are other reasons why the lawn mower can stall at any stage, immediately after starting or during operation.

Other possible reasons

If, with a sharp addition of revolutions, the engine stalls, as if zabulae, then the reason may be:

• Carburetor adjustment failure. This happens after prolonged downtime or after excessive loads, for example, natives in hot weather or in conditions of strong dustiness.
• Clogging valve on the tank cover. Eliminated by replacing the lid or cleaning valve.
• Weakening of the cable of the carburetor regulator drive.
• Stretching of the fuel hose.
• Depressurization of traffic jams on the tank, which includes hoses.
• The clogging of the sapun.

When looking for the reasons why the trimmer stalls for the grass when trying to increase speed, other reasons may appear, for example, associated with the ignition coil and candle. If the fuel mixture is not prepared according to the rules using cheap oil or poor.quality gasoline, the proportions are not observed, or the mixture cooked a month ago, then the engine can also stall when trying to add gas.

How the real reason is determined

In the case when the carburetor is responsible for stopping the engine, a sudden stop is accompanied by a nearby symptoms. Most often, this is the appearance of tangible vibrations in all operating modes. Carburetor adjustment is carried out using two screws. idle control and fuel supply. In which direction to rotate them should be written in the operating instructions. If independent adjustment has not helped, contact the service center or buy a new carburetor.

If you have a lawn mower of a professional or semi-professional class, for example, the same echo or al-ko. then the carburetor resource is approximately equal to the durability of the motor and there is no need to buy a new one. It is enough to seek help in adjustment to a knowledgeable specialist. Motokos type Champion has a slightly lower carburetor resource, it may happen that adjustments will not help. Carburetors of two.stroke engines in the repair are complex, so it is better to order a new.

After making sure that the carburetor works fine, but the lawn mower still stalls, try to loosen the gas tank cover. If the engine operating mode has changed, it means that the lid valve is clogged or clogged. Practice shows that it is useless to clean it. It is better to buy a new cover, it costs a little, and it will last at least 2. 3 seasons.

Along the way, check the tightness of the gas pipeline connection from the carburetor and tank. Sometimes hoses stretch, and air is sucked around around the fittings. With a sharp press on the gas key, the mixture becomes depleted (gasoline is less than a stichiometric indicator) and the motor stalls. This also happens when the gasket between the carburetor and the cylinder is pierced or the bolts of the carburetor attachment are loosened from vibration. Just in case, check them, but do not forget that two.stroke engines are made of rather fragile alloys. If you overdo it with the moment of puffing, the thread in the cylinder can be disrupted.

It is also recommended to check the fence mesh on the hose in the tank, the cork through which the hoses are inserted into the tank and blow the fuel lines. Perhaps they are clogged and a little gasoline enters the carburetor. Especially with sharp pressure on gas.

Having checked and cleaning all the systems of the trimmer for the grass, season the tank prepared by all the rules by the mixture and start from the cold state. Let me work out for several minutes at idle and try to mow fishing at medium speeds. After 10. 12 minutes of work, add speed sharply. a trimmer for grass should not stall. If this happens, change the spark plug and perform the same actions.

If during operation a trimmer for the grass, before stall, spontaneously periodically reduces or increases the revolutions, “failures” appear in power, then it is necessary to check the ignition coil and contacts of all wires. Start with contacts, they are quite fragile and can break off or oxidize.
