Adjustment of the carburetor of a gasoline trimmer for the grass forward. Carburetor setup…

Device and adjustment of the carburetor on benzocos and trimmers

Check if the start button is turned on, whether the oil button is enough, whether gasoline is poured into the tank. If the motor is still not starting, rinse the gasophiller (sometimes it should be replaced if a large blockage is detected), check the candle for performance, clean the air filter.

It did not help? Set up the carburetor air damper to position C, this solves the problem of fuel transfusion. In the case of the “persistence” of the motor, just drain all the fuel from the system and fill the new one, making sure that it has proper quality. Making all these processes solves the problem of launching a motor in 80-90% of cases.

If the motor refuses to work at idle, first of all adjust the carburetor and rinse the air filter. this in most cases solves the problem. If the situation is repeated, then most likely you poured poor fuel into the fuel tank, then drain it and fill the tank with a new.

How to get a lawn mower and make it work if engine speeds are not gaining, and it stalls? First, check if the cutting shaft is clogged with waste and weeds. If everything is in order with the shaft, wrap the air filter or change it to a new one, if the first seemed to you too contaminated. By the way, washing the air filter and gasoline should be washed, which makes the gasket more elastic and prevents the drying of the material.

If, having done these procedures and pressing the starter for the lawn mower, the lawn mower stalls again, then the case lies in an incorrectly adjusted carburetor device. Read the last section of this article, it tells how the carburetor is adjusted on the benzokos.

If there is no spark, put a spare candle to check what exactly is the matter. Когда запасная свеча при установке правильного зазора также не выдает искру, значит дело в оборудовании косы для травы. Repair of the lawn mower in the event of a malfunction begins with the check of the wire leading to the candle.

Carburetor adjustment

This aspect is always needed when the lawn mower is set up. A correctly configured carburetor is the key to the successful operation of engines for the lawn mower.

Despite the fact that the question of how to adjust the carburetor on a benzocos, it seems, to beginners are incomprehensible, but the repair of the lawn mower often ends with this procedure, since the reasons lies in the wrong adjustment, and the repair of the lawn mower and the methods of eliminating them in the settings for configuration. By the way, the run.mowing is also involved in the adjustment of the carburetor.

To understand how to correctly configure a gasoline carburetor for motorcycles, you need to know:

• The device contains three screws: right (l), lower (t), left (h).
• A properly configured carburetor operates on idle evenly and without changes with cold and hot motor, as well as with a sharp descent or set of revolutions. The screw t is responsible for the idle.
• The screw l is responsible for how much the fuel mixture will enter the combustion chamber at low speeds. When adjusting, the screw turns counterclockwise by a quarter turnover.
• Fuel adjustment at high speeds occurs by screw h. For configuration, give out full gas, opening the throttle. Turn the screw clockwise until you hear a speed drop. Then, scroll through the screw in the opposite direction so that the engine works unevenly, after which begin to slowly turn the screw clockwise until you start to hear the smooth and uninterrupted operation of the motor.

The correctness of adjustment is determined even by the color of the working part of the candle. If the tuning of the carburetor is made correctly, then the candle will be clean, without soot.

How to sharpen a knife or disk for a gas station?

To sharpen a knife or disk for mowing equipment, know that a good disk or knife must be sharpened so that the edges become sharp, but the metal was not overheated. The sharpened cutting element will provide easier removal of the grass surface. Also, the sharpness of the disk or knife affects the number of plants that will be eliminated by one capture.

In general, the maintenance of a gasoline braid for grass provides for constant cleaning of equipment after work, checking the quality of oils and gasoline, as well as a properly configured carburetor. Do not pour doubtful additives and the like into the lawn mower. Regularly make the reducer lubrication and lubrication of driving elements to prevent problems. It is recommended to update lubrication, at least every 1000 hours of work.

Causes of carburetor breakdowns

When operating, motorcycles (for example, “Patriot” or “Union”) can be damaged, and the user will need to repair it on its own or with the involvement of specialists. This can happen for a number of reasons. One of the most common is non.compliance with the rules for using the device. If, with prolonged operation of the trimmer for the grass, the carburetor was not used and adjusted, the device breaks.

Another cause of the breakdown is an incorrectly prepared fuel mixture. Often the owners of the equipment buy oil and prepare fuel according to the recommendations written on the package of combustible materials, which is incorrect. When preparing fuel, you need to consider the instructions for the operation of the Motokos itself. In addition, the mixture “by eye” should not be made, since incorrect proportions also lead to breakdown of technology.

Most of the breakdowns of carburetors are equally characteristic of motorcycles of different brands, whether Echo, “cedar”, Homelite or the device of another manufacturer.

Adjustment of the chainsaw carburetor away from the service workshop

Instructions on how to set up a chainsaw. there is in the technical documentation for your tool. Nevertheless, we will consider typical operations to improve the tools of the tool.

Carburetor adjustments are located in an accessible place. To get to them, there is no need to remove the case cover. In different models, holes for adjustment can be located differently, the illustration shows a typical combination.

The settings procedure are as follows

The screw “t” is designed to configure the engine in idle mode. On different models, it can be designated as “la” or “s”. The parameter is exhibited, rotating the screw in the left side to the state of sustainable work at minimum speeds. If the engine stalls, you need to take a screw a little to the right side. The working shaft when working at idle should not rotate.

If when adjusting the chain moves off, unscrew the screw back a quarter. The more precisely you will catch the moment when there are very few revolutions left before the chain movement, the more economical the fuel consumption will be.

The “L” screw sets the degree of acceleration of the chainsaw when pressed on the accelerator. When you open the throttle, the turns must smoothly increase to the maximum value. If the chainsaw stalls at load, this is a sure sign of an incorrect installation of an acceleration regulator. It is necessary to unscrew the screw counterclockwise a little, achieving smooth confident acceleration when opening the accelerator.

The screw “H” limits the speed of the working shaft. If you do not fix this value, the ignition is a failure, and the chainsaws will work with jerks, or as the lumberjacks say. “Divine”. This mode can lead to injury.

In models with a simplified design of the carburetor, the adjustment of acceleration and maximum revolutions may be absent. In this case, all the operating modes of the internal combustion engine are installed by the idle screw.

Signs of proper adjustment

• At idle speed, the working chain remains motionless. When adding “gas” immediately comes in motion;
• When the accelerator is opened, the chainsaw engine instantly accelerates. The acceleration process occurs evenly, quickly reaching the maximum;
• When reaching the limit revolutions, the saw works smoothly, without jerking. The sound of the engine is uniform, without detonations;
• The exhaust is clean, a little sized in color. When the speed changes, only the intensity of the exhaust grows, the color does not change.

The procedure for setting the carburetor of the chainsaw Partner See in this video.

If you managed to adjust the carburetor without analyzing the chainsaw case, and the symptoms of malfunctions are gone. continue to work further. If not, you have to remove the top cover of the tool and dismantle the carburetor.

There is an air filter inside the cover. As a rule, this is a piece of foam rubber or similar material to it. Try not to clog and do not wet the filter. Then carefully disconnect the fuel and the accelerator cable from the carburetor.

Make sure that the fuel does not get into the body. Try to catch the remnants of gasoline from the hose using a clean cotton rags. Then it is necessary to remove the carburetor from the case, and lay on a clean surface for disassembling and washing.

Try to remember (and it is better to measure and fix on paper) the position of the installation screws. Otherwise, the adjustment of the carburetor of the chainsaw after assembly will be difficult due to the mismatch of all installations.

After the end of the work, check if there are “extra” parts left on the assembly table, and if the tool was left inside the case.

There are questions, see how to adjust the Carburetor of the Stihl chainsaw.

Features of the launch of Chinese chainsaws on the example of the Hunter chainsaw. A detailed story and a demonstration of carburetor repair, as well as its adjustment.

A chainsaw carburetor is a part of the engine, the purpose of which is to mix in certain proportions of fuel and oxygen with the subsequent supply of the resulting mixture to the engine.

As a result of violation of the work of this part, the chainsaws will significantly lose performance and can even completely fail. If at least the slightest error in the operation of the motor is detected, then most likely you need to adjust the carburetor of the chainsaw.

The running.in the new tool is also of great importance. Failure to comply with the conditions of running.in can reduce the working resource of the device, and in some cases, lead to the jamming of the engine.

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 of which 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 the enrichment of 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.

How the gas mowing carburetor works or the principle of functioning

The adjustment of the carburetor of the Chinese lawn mower is completely identical with the setting of travokosylovs of European, and manufacturers. To cope with the task of adjusting the carburetor on benzocos and benzotrimers, you need to understand the principle of their functioning. How the carburetor works on a benzos, step.by.step and available described below.

• The operation of the carburetor of the lawn mower begins with the supply of fuel through the channel, as shown in the diagram
• The absorption of fuel into the carburetor occurs using a pulse channel connected to the engine card. Due to the vacuum of air, a flexible membrane is moved under the number 4 in the diagram above
• Through valves 3 and 5, fuel supply occurs. The valve 3 is inlet, due to which the fuel is supplied to the sub.sector, and the valve 5. the exhaust
• Further, the fuel moves through the channel and, passing the filter of thin cleaning, reaches the needle valve 14
• The needle valve is connected by means of a lever with the control membrane 18
• The needle valve is driven when exposed to the membrane. When it is necessary to pump up the fuel in order to start the engine, it is necessary to affect the soft cover of the manual pump. When exposed, the needle is opened, and the camera is filled with the fuel mixture
• Когда же двигатель запускается (на холодную), то открытие иглы происходит за счет разрежения при закрытой воздушной заслонке. This vacuum affects the nozzle nozzles and high speeds on the membrane 18
• The membrane acts through the lever on the needle valve, through which the camera is filled
• After starting the motor, the air damper opens, as a result of which the engine operates on the depleted mixture, since the fuel is mixed with air
• The fuel mixture with a filled chamber is supplied (sucked) through the nozzle jetlays and medium revolutions (when the engine is launched)
• The throttle shift at the same time shifts from the original position by 10-15 degrees
• When the work is carried out under load, then the fuel begins to enter the chamber through a nozzle nozzle, and at the same time the throttle shift turns to an angle up to 90 degrees (depends on the force of pressing for gas). In all operating modes, an air damper should be open, through which the fuel is mixed with air, and thereby there is an ignition of the mixture in the cylinder

The following shows the principle of operation of the carburetor of the lawn mower. Based on the scheme, you can not only deal with the principle of operation, but also identify breakdowns and other malfunctions of the mechanism.

When operating the tool, it is necessary to take into account the presence of another nozzle. This nozzle is located between the channels of the idle and full power. It is necessary in order to exclude a strong impoverishment of the mixture, which occurs in the case of the engine at an incomplete load. In such a situation, the occurrence of a back of a pair is not excluded. Through the additional channel (nozzle), fuel is sucked into the chamber, through which the fuel-air mixture is enriched. Below is an additional nozzle, which is indicated by the number 1.

Having an idea of ​​the design of the membrane carburetor of Motokosa and the principle of work, it will not be difficult to configure it with your own hands. To adjust the carburetor of the lawn mower, adjusting screws are used. The scheme above shows two screws for configuration, but most modern models of gasoline trimmers are equipped with three screws. The presence of three setting screws allows you to perform a more accurate adjustment, while achieving stable and uninterrupted operation of the internal combustion engine.

It is interesting!What is the difference between a trimmer and a benzoca? Many people believe that a trimmer for grass is low.power electrical herb. However, a trimmer for grass is a generalized name for benzos, motorcycle and electric braids, as they are designed for general purposes.

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:

Flamming fuel supercharger

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.

As a result, the internal space of the fuel pump is contaminated from the side of the pulse channel.

Ground of a mesh filter

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

The failure of the adjustment lever

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 is spoiled

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.

Clogging the adjusting space

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.

The adjustment membrane is spoiled

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.

The inlet regulatory lever sees

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.

The shutters become unusable due to incorrect service of the air filter or its breakdown.

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 carburetor cannot be adjusted

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.

The device of the carburetor of the lawn mower

The basis of the carburetor of the lawn mower is an aluminum corps. It has a diffuser (hole with internal contours). Air is pumped through this hole. The speed of oxygen (air) is dependent on the cross.sectional (passage opening) of the diffuser.

The diffuser is equipped with fuel channels. Fuel is drawn from them using air flow.

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.

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.

Adjusting the gas mowing carburetor: the main points WAS Last Modified: June 25th, 2020 by administrator

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.

Assembly of a carburetor

Collecting a carburetor of motorcycles is completely easy. It is necessary to perform all actions in the reverse order:

Step 5

In the cover of the carburetor, install a spring and a needle valve. Holding your finger to tighten the mounting bolt.

Step 6

Screw to the product body with two screws the air supply system valve.

Step 7

Turn the carburetor and proceed to the assembly of the fuel system system. First you need to put the gasket.

Step 1

Step 2

Set a plate with a manual fuel pump button and tighten four screws.

The carburetor is assembled and ready for further operation.

For the first time, the repair of the carburetor Motokos may seem like a complex process, but if you have to disassemble it a second time, then this procedure will not cause much difficulties.

If you have not found any of the above problems in your carburetor, it is recommended to seek help in a specialized service.

How to adjust the carburetor of the lawn mower with your own hands

Adjustment

• Run the motor. When it is launched on the XX, knives should not rotate, but if the opposite occurs, then we reduce the speed of the idle.
• We adjust the screw l. He is responsible for the mixture at low speeds. First, scroll to the stop clockwise, then unscrewed 90 degrees against the sentry. If you find failures, we repeat this action, weakening it for 1/8 part, that is, 45 degrees.
• Adjust the La screw, more frequent name. t. With an increase in speed XX, more air is added to the mixture. Power is lost. But if there is not enough air, fuel is burned worse. We unscrew the screw so that it works perfectly at low speeds, while the knives should not rotate. In the process of setting, you need to feel momentum, it should work stably on XX.
• Adjust the screw h, which sets up the mixture at high speeds. To identify their maximum quantity, we use a tachometer. Upon reaching the largest number of engine speed, we unscrew the screw to the left by 180 degrees, the adjustment on this ended.

Sometimes only the correct setup and the use of the device reveals its entire potential. No need to neglect it and conduct as necessary.

The spring may interfere

My first attempt to adjust the carburetor of Kustoreza failed, as the spring of the fuel mixture adjustment propeller interfered. The factory spring in a compressed state was too thick and did not allow to reduce the supply of fuel to the required level. I had to take another spring and, after replacing, continue adjustment.

Fuel mixture adjusting screw spring

In the photo above the factory spring, below the adjusting screw with a selected spring. I write about this because I am not sure that this is an isolated case, and someone else may face the same situation.

From personal experience

lawn mower or trimmer for grass

Castorer. This is a broader concept than a bureau (bureau), since it can also be electric. Gasoline lawn mower and gasoline lawn. This is the same.

Some authors claim that the bush cutter is a weaker tool than a more powerful gasoline cutter that can cut the bushes. Personally, I have a tool with a maximum power of 1.7 kW, capable of, as indicated in the instructions, mow small bushes up to 10 mm thick. User manual is called “gasoline lawn mower”.

The proportion of the fuel mixture

I read somewhere that if in the instructions for benches and the oil tank different proportions of the preparation of the fuel mixture are indicated, it is necessary to use the proportion specified in the instructions.

For a long time I did so. Excess oil dripped from the engine to the gas tank, and the fog was constantly formed on the spark plug, since the manual indicates the proportion for the engine run at 1:25, and on the container. 1:50. After the transition to a ratio of 1:50, the appearance of oil fluxes disappeared. The spark plug continued to burn, but with less intensity (the carburetor has not yet been regulated).

Until now, some users of gasoline instruments determine the proportion of the fuel mixture “by eye”. If the amount of oil is underestimated when preparing the mixture, after some time, immediately after the engine starts, an extraneous noise may appear, which gradually disappears when warming up, and the engine stops with a sharp jerk. Continuation of the use of a bushrer in this mode will lead to its failure.

Clead cleaning

In the worst days of the Differter with an unregulated carburetor, the engine stopped after each full fuel tank. And only after cleaning the spark plug from the carbon, could you continue to work.

Thin sandpaper was used to clean the electrodes, and a thin stationery clip with one bent end was used to clean the space between the insulator and the case. First, the electrodes were removed with a rag of large dirt, then polished with sandpaper. Subsequently, the spark plug was dipped into diesel fuel, and the moisture soaked was scraped off the paper clip from the insulation surfaces, from the inside of the body and between them. Then the light of the ignition was dipped several times into diesel fuel, which was then shook off with dirt. Sometimes the procedure for cleaning and rinsing the brackets was repeated.
