Adjusting the new Carburetor of the Champion grass. Do -it -yourself repair…

CHAMPION TRAMMEN

Greetings to all readers! Today we’ll talk about the 4th tenth trimmer Champion T334FS. I do not often have to deal with him, but the problem with which I ran into the first, I was not very pleased.

It all started with the fact that my comrade wanted a trimmer for the grass but did not want to bother with the targeted mixture and electricity, of course, we immediately immediately rest against the 4-stroke motorcyclain, namely, in that trimmer for the grass, which will be discussed.

After the season for repairs, I received this trimmer for the grass, I could not dismiss :)). In general, I stopped starting if there was no compression at all. Well, I think everything stuck, I decided to take up the repair interesting :))

When he opened the valve cover, it became clear right away, the puck (cracker) fixing the outlet valve became the fault, it fell out and the return spring flew and flew off. At first I thought to disassemble, but then I decided that you could do not disassemble. I will be happy to share how to do it, for start, let’s figure out why this method is applicable.

Valve location in the cylinder

In fact, the cylinder of this trimmer for the grass is not much different from other 4-time trimers of Chinese manufacturers.

On the example of the CPG, the STIHL 4MIX CPG see that the valves are located at 90 degrees parallel to each other (the intake graduation, red and blue noted the nodes what needed to be installed), the gear is responsible for the valve, which is brought into actions with a gear belt through the leading gear to Kolenvalu, a led gear, in turn, through towing levers passes the efforts to the stag of the pusher. In the picture we see that the valves are located from the top of the piston, so the piston itself and wakes up to serve us with an emphasis for the valve.

It is very important if you still decide to remove the gear, you need to put it correctly according to the TMT marks, otherwise the valve will be opened at the wrong time, or they will completely be applied to the piston.

Closer to business

We unscrew the spark plug. We take a 3 mm thick cord (the cord is well suited from the generator starter, etc.e) we make nodes about 1 cm from each other (it will be easier to catch the valve, I have enough 4pcs) such a thickness so that at the time of installation through the openings of the candle the piston rests between the knot and valve, now we shoot the eyes of the valve and stuck the knot under it, we catch the place valve, that is, we put the piston in the vehicle and thereby block the swing knot, we block the valve, now we calmly install the spring and then we turn the puck in the right direction for fixing. Thus, you can easily put the puck on the valve, so that at the moment when we rush into it, it did not fall into the bottom. Perhaps someone has hidden a simpler way, I will be glad if you share.

I hope this will help you accelerate the repair, I had to spend a lot of time to analyze and prepare a trimer to remove CPG. See you, follow your assistants.

Adjusting the valves of the lawn mower, trimmer for grass

Adjustment of the gaps of valves of the four-stroke engine of the lawn mower using the example of a gasoline trimmer for grass Hope farmer VS-350 4T.

Unfortunately, in the instructions for the operation of a gasoline trimmer for the grass, Hope Farmer VS-350 4T does not mention the need to check the gaps and the method of adjusting the valves.

In fact, checking valve clearance is required after 10 hours of operation of the new engine and, then, every 50 hours of operation of the lawn mower.

The gap between the rocker and the valve rod should be 0.08-0.15 mm. This applies to the intake and graduation valves.

We will use the probe with a thickness of 0.1 mm to check the gaps and adjust the valve adjustment.

Carburetor device

The lawn mower (lawn mower) contains the basis. the case of aluminum, which houses the rest of the parts, coordinated as a whole. The carburetor housing has a diffuser. a move with internal channels through which air is pumped.

The larger the cross section of the diffuser, the more actively, oxygen is supplied along with the air-an oxidizing agent in which fuel burns (gasoline mixture).

Channels branching from the course of the diffuser deliver fuel, with which the heated air is mixed, which carries away the vapors of gasoline. Outside the main compartment of the carburetor are placed:

The latter and forms the same rattling mixture ignited in the combustion chamber of the carburetor.

Principle of operation

The order of injection and filtering of fuel in the engine of the lawn mower is next.

• With the help of a throttle, the amount of air supplied to the diffuser is set. The more air is supplied, the more oxygen needs gasoline for combustion, and the greater the power released in the form of heat. The energy of the heat is further converted into a mechanical.
• The membrane pump pumps the required amount of gasoline.
• Next, gasoline passes through the engine fitting.
• Fuel passes through a retractable and exhaust valve.
• Fuel is filtered using a mesh filter.
• Through the needle valve, it also enters the camera with the membrane.

The stages of the carburetor is as follows.

• Air enters the pipeline with an air conditioning. The damper sets the desired air flow intensity.
• The diffuser is narrowed in the node of gasoline’s injection. this is necessary to give a higher air flow rate.
• Fuel passes through the bastard compartment and passes the jet, falls into this narrowing of the tube. The float compartment doses the supply of gasoline. In this compartment, the pressure is in a state of equilibrium. In a narrowed tube, it decreases. Due to the difference in both values ​​of pressure gasoline and passes through the jetler.
• Accelerated stream sprays gasoline, converting it into aerosol pairs. The resulting gas-air mixture is ready for a rowing in the combustion chamber.
• Having passed through the fuel pipeline, this mixture is in the cylinder of the carburetor.

Conclusion: To set the required power, first of all, you will adjust the rate of combustion of fuel using an air damper. If the gap is too small, and the oxygen in such a mixture is less than 10%. the fuel does not burn, therefore, the engine will not start or immediately staller.

In the case of buying a Chinese trimmer for grass, it is worth considering that it differs little from European- the same 2- or 4-stroke engine and drive.

However, the quality of the details is saved, forcing the consumer to change them more often. Check what compatible details offer non.Chinese companies for your device.

About adjusting the carburetor motorcosa: how to set up and adjust with your own hands

Motokosa carburetor adjustment is a process that needs to be mastered for the full operation of a trimmer for grass.

Trimmer for grass is a completely simple device that can break in only a few places and demand a mechanical repair or replacement of part.

Adjustment of the carburetor device of the float.type motorcycles may require knowledge of certain subtleties. The nuances due to the model and the specifics of its functioning will ensure a clear mixing and supply regime of the fuel mixture.

What is the problem of a trimmer malfunction for grass

CHAMPION BAS carburetor, how to adjust? This is just a trimmer for floating type grass. a common option designed to mix air and fuel in the proportions provided. The main problems arising during the operation of the motor are approximately similar to the problems that overtake the carburetor in the car:

• the motor can stall immediately after it managed to start. The reason is that gasoline is supplied in insufficient quantities. This is called “poor” fuel;
• Excessively fed gasoline leads to its incomplete combustion, excessive density of the mixture and uneconomous consumption.

Important! It is necessary to regulate the carburetor under different circumstances: a change in the temperature regime, octane fuel or type of oil, after winter or end of the run.in, load or spontaneous turning of the screws from strong vibration of the body. Some owners prefer to configure the module before each use to make sure of its correct work.

Trammer device for grass

The float carburetor consists of an aluminum case with a hole (diffuser). Air injection is carried out through its passage hole, and gasoline is pulled through the fuel channels along with the air flow. This is the basis of the device. fuel chamber. The nozzle installed on top, the pump and the mixture adjustment system provide not only its saturation, but also the uniform supply.

Note! The float carburetor has been used for decades, and the main problems of all types are similar. The principle of functioning of the device depends on the quality of the mixture, and the setting is aimed at ensuring it.

How to adjust a trimmer for grass on a motorcycle

Most modules have adjustment screws, and the scheme usually helps to understand their functionality:

• L. for fuel supply of low.speed mode;
• H. the supply of fuel at high speeds and its consumption;
• T. debugging idle revolutions.

Motokos adjustment, the production of which is Chinese, can cause difficulties due to the presence of only one screw responsible for the idle.

Important! The answer to the question of how to adjust the carburetor of the Champion lawn mower, it is better to watch on the video where a professional does it.

Carburetor adjustment on the Patriot trimmer lawmaker

Adjustment of the carburetor trimmer for Patriot grass is carried out by ear screws. No verbal explanation will give a complete idea of ​​how this is done, so it is better to watch a video instruction.

After proper adjustment, the engine should increase the speed, and when working, an idle cutting tool will not turn. Everything is easy and easy!

Adjusting the carburetor of a trimmer for grass Motokos with your own hands

Benzocosils, like all gas.tools for mowing grass, are not considered difficult to maintain equipment. They can and should be configured, repair with your own hands. So, for example, in five minutes of your free time, you can adjust the carburetor of a trimmer for grass.

Often, to configure the engine, you need to adjust the supply of gasoline, and this is done precisely by the carburetor of the gas station. Such a device requires special attention. If you use it, it may refuse to work or will perform its functions with errors and with a large power consumption.

Today we will analyze the main reasons for the breakdown and step.by.step adjustment of the part with our own hands.

How is the carburetor of a gas station arranged?

What is a carburetor? This is a complex detail in the system of operation of the mechanical device. In any model, air mixing with gasoline for future supply to functioning cylinders occurs.

Важно! Самыми качественными и рекомендованными бензокосами можно смело назвать приборы таких брендов: Husqvarna, Hyundai, STIHL, Zama, Walbro.

The engine of the lawn mower is based on an aluminum base that has a diffuser (a recess with internal restrictions). It is through this recess that air flows are heated. The rate of oxygen intake depends on the passage part of the diffuser.

Fuel tracks adjust to the diffuser. Gasoline is drawn through them using air flow. But on the outer part of the engine, the following parts are installed:

Важно! Плотность воздуха в карбюраторе зависит от объема открытой к доступу заслонки. Чем больше открыта система заслонки, тем больше агрегат расходует бензина и тем выше его мощность. То есть настройка карбюратора на триммере – это создание оптимального поступления топлива за счет правильной подачи воздуха.

When you need to adjust the carburetor in the trimmer?

You need to configure the device in such cases:

• The new engine used 5l fuel mass in one call.
• The weather has changed (a sharp drop in atmospheric pressure).
• You bought oil or gasoline of another brand.
• During long.term storage.
• After the vibration, the screws independently got out.
• Gasoline consumption has increased, the carburetor began to pour fuel.
• The appearance of soot on the electrodes of the inner candle of the device.
• Gasoline stopped entering the cylinders.
• The motor often stalls or does not gain enough speed.

What are the breakdowns and how to recognize them?

One of the problems of failure of the trimmer engine for grass may be a mesh filter. Only two breakdowns can be attributed to this element:

To identify the exact cause, you need to do a number of the following actions:

• Unscrew the lid of the fuel air gateway to take out the mesh filter. If the mud is detected, rinse it in the fuel or purge carefully. If you see serious damage to the mesh filter case, you need to install a new one without hesitation.
• If the pipe broke down to supply the compressor fuel, then you should check this part. Most often it requires periodic replacement due to its low strength.
• To clean the starting part of the carburetor from blockages, you need to use acetone or gasoline. You can also blow the components of the device with compressed air. this is the easiest and most convenient way to repair.

Важно! Основание дроссельной заслонки, впускные и выпускные клапаны, места соединения всех частей карбюратора можно проверить простым действием – смазать проблемную зону мыльной пеной.

Self.adjusting the carburetor on the trimmer

Before setting up the device of the gas station, we recommend that you do the following actions:

• Clean and rinse the engine.
• Check for suitability of the spark plug.
• Remove dust and dirt from an air filter or change it to a new.
• Put in a trimmer video a cord suitable in diameter or install well.sharpened knives.

After installing the cutting parts and the launch of the fuel engine, the carburetor needs to warm up within 10 minutes. In case of rotation of the cutting tool during idle operation of the engine, reduce the engine speed.

Carburetor adjustment on the trimmer is not easy and laborious work. For competent configuration, you will have enough information from our cognitive article. And to do everything efficiently, use the video in which the whole process is clearly shown.

Carburetor for a trimmer for grass. How to adjust the carburetor of a trimmer for grass.

On trimmers, in addition to electric motors, gasoline internal combustion engines are installed. This mechanism requires special attention, since if it is incorrectly set up, it will either refuse to work or work with interruptions and power loss. Basically, the engine setting is to adjust the supply of fuel, and this is done using a trimmer carburetor for grass.

The standard design of any gasoline trimmer for grass must include a fuel system, the basis of which is the action of a standard carburetor. Its device and the initial principle of action are almost the same for all motos, regardless of their design characteristics and purpose.

The carburetor of the motorcycles consists of an entire.metal aluminum corps, which protects the internal components of the node from moisture, fine debris and dust. In the lower part of the case, a built.in diffuser is provided, the second name is “Venturi’s nozzle”. The main function of this regular part is the supply of air in the amount that is required by the fuel node to enrich the fuel. Diffusure work on a simple principle: the smaller its diameter becomes, the more intensively the air is absorbed. This is due to the fact that in the zone of the smallest diameter the level of air discharge becomes maximum.

The upper part of the built.in factory diffuser is pre.equipped with fuel tubes, according to which, under the influence of air, the fuel mixture is delayed. The remaining parts of the carburetor: regular adjusting screws and fuel pump can be located both inside and outside the carburetor.

The device of the carburetor Motokosa includes a throttle, the main task of which is to adjust the volumes of absorbed air. The larger the amount of air, the higher the rated power of the power unit of the trimmer for grass. Another damper function is to relieve the cold start of the engine. If the lawn mower is started for the first time after prolonged downtime, then the damper must be closed. Immediately after starting the motor, the part must be opened, otherwise the ICE will stall.

The carburetor for a trimmer for grass is equipped with a pulsed channel, which connects the internal cavity of the ICE crankcase with the pulse chamber of the pump. The piston located in the motor cylinder creates reciprocating movements, which leads to phased changes in pressure inside the crankcase. At the same time, a membrane is set in motion. Thus, the action of the pump is completely synchronized with the operation of the power unit.

A standard carburetor membrane takes an active part in the fuel suction. In the fuel node, it gets through the fitting. After that, the fuel passes through the built.in intake and exhaust valve, then through the mesh filter and fuel tube. Then the fuel flows next to the needle and gradually fills the camera equipped with a control membrane.

The standard valve of the carburetor trimmer for the grass is connected to the membrane using a lever. Below the built.in membrane is a cavity into which the air is absorbed through a special hole.

The carburetor for the lawn mower is working on this principle in stages. This ensures the continuous operation of the fuel unit and the uninterrupted supply of fuel in the cylinder of the standard power unit.

Когда требуется настройка карбюратора бытового триммера для травы? It is necessary to adjust the built.in carburetor of a trimmer for grass with:

• running a new engine, during which from 4 to 5 liters of fuel mixture were used;
• sharp changes in the weather;
• changes in air vacuum. for example, when a lawn mower is often used in mountainous areas;
• prolonged simple trimmer for grass;
• intensive growth of loads on the power unit Motokosa;
• arbitrary twisting of the built.in adjusting screws of the carburetor. this becomes the cause of increased vibration of the internal combustion engine;
• change in the quality of the components of the fuel mixture;
• transfusing a fuel by a carburetor, a result of which is an increase in fuel consumption;
• the regular appearance of the thick layer of tarry deposits and soot on the surface of the electrodes of the standard spark plug of the trimmer for grass;
• starting the engine and its arbitrary shutdown or slow speed;
• lack of fuel intake into the cylinder of the power unit;
• increase in the volumes of ejected gases.

The lack of timely tuning of the carburetor threatens the serious breakdown of the trimmer for the grass, up to the full failure of its factory engine.

Do.it.yourself carburetor adjustment. Periodic adjustment of the carburetor of the trimmer for grass should be performed on the served and completely serviceable power unit. Before starting the procedure, the operator must thoroughly rinse the details of the internal combustion engine and inspect its CPG for the presence of burrs or other defects. In addition, you will need to clean or change the spark plug, as well as rinse the filter elements in the design of motorcycles.

During the tuning of the carburetor, the engine of the lawn mower should operate under a certain load. It is best to install a cord of the corresponding diameter or cutting knives on a trimmer for grass.

After the installation of the cutting organs, the operator must start the ICE of the trimmer for the grass and leave it to work for about 10 minutes. If during the operation of the power unit at idle, it was noticed that the cord or knife rotates, then it is necessary to reduce the speed created by the engine. To do this, turn the lower regulator, often indicated by the letter “t”, to the left side, until the installed cutting organ is completely stopped. The further settings of the fuel node are as follows:

• The “l” regulator, located on the right, is responsible for enriching the fuel mixture by air during the operation of the motor at low speeds. The position of this screw must be configured first. To do this, the operator will need to achieve maximum engine speed when working at idle. for this you need to alternately turn the “l” screw in the right or left side. As soon as the maximum revolutions are achieved, the screw will need to be turned to 1/2 turning to the left;
• The screw “t” or “LA” is necessary to adjust the idle. During its turning to the left, the power unit will decline, and when turning to the right, respectively, increase;
• The H “H”, provided on the left, is responsible for the enrichment of the fuel mixture by air during the operation of the ICE of the Trimmer for high speeds. This screw is also needed to configure the power of the motor and the volume of the consumed fuel. The setting of its position is carried out by turning the screw to the right or left sides until the maximum permissible engine speed is reached. After that, the screw “h” will need to turn 1/2 turn to the left.

Principle of operation

The flow of air entering the tube with a throttle fabric intensifies or weakens depending on its position. From the fuel chamber, gasoline enters a special tube through a jetler. Float. a device that regulates the supply of fuel, its level determines the volume. Gasoline supplied through a jickler, under the influence of the pressure difference, is mixed with air. So it turns out a fuel mixture for engine operation.

note! The wrong fuel composition is due to a lack of gasoline or air. This means that you need to configure the throttle or the fusion position. The motor can stall due to the jet, but this is a more serious breakdown.

Benzotrommer carburetor repair tips

Spring of the adjusting screw

For example, the setting method described above may not give positive results with an overly large number of turns of the mixture supply spring and, as a result, the impossibility of optimal reduction in the level of gas supplied. To eliminate this, you can independently shorten the spring or, in accordance with the operating manual, purchase a new.

Oil for gasoline trimmer for grass

So, often the information indicated on the bank by mixing gasoline with oil differs from the instructions in the passport of the trimmer for the grass. As a result of this, a black fog can quickly form on the spark plug, which leads to a drop in power and an increase in fuel consumption. Therefore, when preparing a working mixture, the recommendations specified in the operation manual should be followed. In most cases, the proportion for the chopped ICE is 1:25. It is worth noting that many tool owners prefer to prepare fuel “by eye”, which will certainly lead to the rapid wear of the piston braid for grass in the case of a decrease in the portion of oil and the formation of soot on the spark plug with an increased amount of lubricant fluid.

The principle of operation of the carburetor of the lawn mower

The throttle dashes determines the amount of air for supply, and the engine power directly depends on this.

Fuel is sucked into the carburetor system (its membrane). Then passes through the fitting in the carburetor. Next, the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. The needle valve moves into the membrane chamber.

• Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
• The fuel supply system is necessarily narrowed by a diffuser to increase the flow rate.
• Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already low. Thanks to the pressure drop, fuel penetrates through the jetler.
• Air flow acceleration contributes to the transfer of fuel (gasoline) and its spray. As a result, the air-fuel mixture of the necessary proportion or density is formed.
• The air-fuel mixture penetrates the engine cylinder through the fuel tube.

The level of air density in the system depends on the area of ​​the open air damper. The wider the damper is, the greater the fuel consumption and power.

Simply put, adjusting the carburetor on a benzocos. creating an optimal fuel mixture due to the correct air supply.

How to adjust a carburetor on a gas tank

Before adjustment, it is necessary to carefully clean the filters according to the maintenance in the instructions.

Further configuration of the carburetor of the lawn mower with your own hands is performed by adjusting screws. There are three of them:

Right (l). adjustment of the fuel mixture for low revolutions.

You need to find the maximum speed at idle. To do this, they slowly turn the screw (l) to the right and left.

For adjustment, the screw is rotated by a quarter of turning must be counterclockwise.

Lower (t). is responsible for adjusting the engine at idle.

For proper adjustment of the idle, it is characteristic:

• Sustainable operation of a cold engine;
• non.high speed of the hot engine;
• for a trimmer head, a large supply supply;
• Sustainable engine operation when changing positions (sharp rise or descent of a knife).

Left (H). adjusting the mixture at high speeds. (The screw is set up last).

The overall adjustment of the maximum revolutions, engine power, temperature and gas consumption depends on the left screw (H).

Setting a carburetor of a lawn mower with a last screw is performed as follows:

• Open the throttle to the full, while issuing a full gas. Turn the screw clock until the speeds fall (in this case, they are oriented by ear).
• Turn the screw as slowly against the clock until the non.uneven operation of the engine.
• Then turn back very little, barely hearing a stable, even work.
• For more visual use of skills, it is more convenient to consider the work of an experienced user:

It is interesting that from the point of view of the author of the video, the configuration (its correctness) is determined by the color of the candle, and not just by the speed and stability of the engine.

Correct tuning of the carburetor with your own hands in this case-combustion of the fuel mixture without a residue, the color of the candle should be light brown.

You can adjust the carburetor of the lawn mower with your own hands

lawn mowers, like the entire bench tool for the garden, is not difficult to maintain equipment. Repair, set up on your own and it is necessary. For example, adjusting the carburetor of the lawn mower with your own hands is the matter of five minutes. The carburetor from the lawn mower is a node in the power supply system. In it, like any carburetors, there is a process of mixing air and fuel (gasoline) for further supply to the motor cylinders.

In this process, the main thing is the correct proportion of fuel and air, for which the carburetor is regulated.

The main problems and malfunctions of the carburetor.

Mesh filter. There are only two problems with this element more often:

In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If dirt just accumulated on it, then flushing in gasoline or purging will help.

With visible damage on the mesh filter, you must definitely put a new. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).

The starting device of the carburetor in most cases does not function due to blockages. Should be used for flushing acetone or the same gasoline.

Purging parts of a carburetor with click of compressed air. permissible and convenient repair practice.

The hull of throttles, the ligaments of the parts of the carburetor, the intake or graduation pipeline. all of the listed parts are subject to depressurization. You can probably check in a primitive way. spread the problem area with soap foam.

The main problems

Malfunctions of the carburetor Motokos or trimmer for grass, despite the relative simplicity of their elimination, sometimes require a long search by excluding. The main reasons are as follows:

The most repeating breakdown is wear, rupture of the membrane. As a result, its lavation. Fuel moves are not sealed at certain stages of the engine cycle. The reasons here are as follows:

• You have been working on a motorcycle or trimmer for too long without a break;
• Poor.quality fuel was seasoned;
• Wheelled gases fall into the pulse channel.

A deformed membrane is fraught with several bad consequences:

• not enough gasoline or oxygen in the created combustible mixture;
• the launch of the motor occurs after 10 or more unsuccessful attempts;
• the engine knocks, clats during operation, and t. D.;
• The working piston is deformed.

The reasons for the clogging of the mesh filter are poor.quality fuel cleaning, damage to the hose and/or the injection head.

Wear of the contact edge of the lever. a consequence of not completely purified fuel, into which grains of sand or particles of clay, metal or other inclusions that are not soluble in liquid hydrocarbons fell. A problem with fuel injection appears, the motor does not function with interruptions without load.

The inlet needle breaks due to the presence of metal and stone particles in gasoline. As a result, the saddle of the intake needle tightly adjacent to it, the fuel mixture flows. In the combustible mixture created by the carburetor, there is too much air, which is why the motor can “sneeze” during operation. Finally, the needle can stop due to poor-quality gasoline, or the unit was idle for a long time.

Deposits may accumulate in the adjustment compartment. The needle does not completely cover the hole, and a lot of gasoline enters the fuel chamber. the motor pours it, perhaps floods the spark plugs. Because of this, the gasoline mixture contains an increased number of vapor of gasoline. The efficiency falls noticeably.

We offer to familiarize yourself when collecting hawthorn. fertile

The membrane is often deformed (sometimes torn) due to continuous operation of motorcycles or trimmer for grass for several hours. If you abuse such a “shock” mode of operation, damage to the membrane occurs more often. New breakdowns will be sprinkled from a cornation of abundance:

• the piston will break;
• The number of attempts by the unsuccessful start of the engine will increase sharply;
• The fuel mixture will contain too little gasoline;
• Useful (thermal) power will drop sharply.

Sequeling of the adjusting lever. a consequence of the incorrect installation, random flexion. Contactive line will find an incorrect position. This will violate the additional injection of gasoline.

The damper has worn out

Throttle and air conditioning are unusable due to admission to the air flow of dust, metal particles, etc. D. Damaged shutters are similar to details subjected to streaming with sand. Due to wear of the damper, the efficiency of the motor decreases, breakdowns are detected. The piston and cylinder wear out.

In some cases, this filter is simply not suitable for your model motorcycles or trimmer for grass. In the end, the shaft of the motor will suffer. its pieces fall into the engine channels, which is why the piston will be broken.

The fact that the adjustment is too rough (it is not possible to accurately set the parameters) are to blame for the adjustment screws. The manufacturer Motokos or trimmer for grass can put excessively thick and hard springs. You can find others either in workshops where such equipment is repaired, or purchased from any dealer or official representative of the company who released the engine for your trimmer for grass or mechanical braid for grass.

The primer broke

Primer-a manual mini-pump for forced swinging fuel into a carburetor. For a successful start of the motor, it may be necessary to pump 20 ml of gasoline manually.

In what cases is it required to set the carburetor?

The stable work of the carburetor motorcosa largely depends on its correct setting.

The assembly adjustment is required in the following cases:

• After the run.in a new trimmer for the grass, when 4–5 full fuel tanks were spent during operation;
• with a frequent replacement by the operator of the brand used to refuel gasoline;
• as a result of a sharp change in the weather;
• due to long-term storage of a trimmer for grass;
• as a result of arbitrary twisting of the adjusting bolts, motorcycles caused by strong vibration of its motor;
• due to a sharp increase in the number of fuel trimmer consumed.

It will also be required to adjust the carburetor of the motorcycles in those cases when the soot quickly appears on the light of the instrument, as well as with a sharp increase in the volume of exhaust gases thrown out by the trimmer.

Elimination methods

The list of upcoming work with the engine may be as follows:

• replacement of the fuel pump;
• disassembly and flushing of the mesh filter;
• replacement of the adjusting lever;
• It is also necessary to clean the adjustment space;
• replacement of the membrane (or the entire block where this membrane is located);
• setting in intake, graduation and needle valves;
• replacement of the damper;
• cleaning the fuel channels and diffuser;
• replacement of springs of screws;
• Change of primer.

Not all these works can be completed. It often turns out that many of them have no need if a specific malfunction is immediately discovered.
