Adjusting the carburetor of a Chinese trimmer for grass with one screw. Maximum speed adjustment

A trimmer carburetor device for gasoline grass

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.

Brush Cutter Repair | How To Set Carburetor Tuning

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.

Repair of the carburetor

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.

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.

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.

How the benzotrimer carburetor works and works

All varieties of carburetors produced by manufacturers of benzotrimmers are almost unrealistic to cover. But, since the design of this module, as well as its principle of operation, is largely similar between different models, you can make a generalized description of the processes occurring in the carburetor. This information will allow the user to understand the principles of the device, eliminate the malfunctions and properly operate.

The basis of the carburetor trimmer for the grass is an integral aluminum case. Below is a diagram of this block.

Below it, there is a diffuser, which is also called Venturi’s nozzle (18). Air is absorbed through this nozzle with a motor.

In the upper part of the diffuser are fuel channels (11,12). Through these channels, the air flow, adds gasoline. The fuel pump itself, nozzles and a system used to adjust the supply of a mixture of fuel with air can be built.in or installed outside.

The throttle flap (9) regulates the amount of air sucked into the carburetor. Its number affects the power that the engine develops. Damper (7) serves for cold launch. It must be closed if you are going to start the unit. After the engine has launched, it needs to be opened, otherwise, the motor will immediately stall.

The pulse channel (1) connects the impulse chamber of the pump to the engine card, namely, with its internal volume. The piston located in the cylinder, producing reciprocating movements, sequentially changes the pressure in the crankcase (vacuum or increase in pressure). Pressure drops make the membrane move (4). Therefore, the operation of the pump is synchronized with the operation of the engine.

The gasoline leaks from the tank occur precisely with the participation of the membrane (4). Gasoline enters the carburetor through the fitting (2). Further, its path lies through the inlet valve (3), the release valve (5), through the mesh filter (6), the fuel channel (10), passes by the needle (14) and fills the camera (16), which has a control membrane (18).

Valve (14) by means of a lever (17) connects to the membrane (18). The cavity that is located below the membrane is connected to atmospheric air through the hole (19).

The device is functioning as follows.

  • During the suction tact, a vacuum is created in the diffuser. This fact causes air leaks. The amount of air entering the carburetor chamber, as well as the engine power and the amount of its revolutions and the amount of its speed, depends on the position of the throttle.
  • At this time, a fuel from the chamber (16) is sucked through the nozzles (11,12), after which it is mixed with leaking air. Gasoline, mixing with air, begins to spray. Thus, a fuel mixture is created.
  • The finished mixture enters the cylinder, where it is compressed by the rising piston and is ignited at the verge of its point from the spark, produced spark plugs produced.
  • Since the volume under the control membrane (18) is connected to atmospheric air through the canal (19), the membrane goes up, opening by means of a lever (17) valve (14). After the valve is opened (14), a new portion of fuel enters the camera (16).
  • After the camera (16) is filled, the membrane (18) returns to its original position, and the valve (14) is closed.

Further, during the operation of the motor, all of the above processes are repeated. To adjust the number of fuel entering the diffuser through the nozzles, a screw is used (13). A screw (15) is also used to set up idle speeds. When twisting the regulators, the fuel mixture is enriched, and when twisting, the mixture impoverishes occurs. Also, in some models of carburetors, you can adjust the idle speed by the amount of the engine by the number. It is usually located on the outside and, when twisting, rests on the lever, fixed on the axis of the throttle.

Thus, using 3 adjusting screws, you can achieve maximum engine performance, as well as set up its uninterrupted operation at any ambient temperature, and even in mountainous areas.

The spring may interfere

My first attempt to adjust the gas mowing carburetor did not give anything, since the spring of the fuel mixture adjustment propeller prevented. The factory spring turned out to be too thick in a compressed state and did not make it possible to reduce the supply of fuel to the required level. I had to choose another spring and continue the adjustment after its replacement.

Signs of unbalancing

Carburetor debugging is necessarily carried out in the manufacture of the device. As a rule, the owners will learn about the need to adjust the fuel supply with their own hands only after quite serious breakdowns, in the process of correcting which, the module was removed and, for example, cleaned.

Signs of failure in the settings are the following:

  • starts up, but immediately stalls the engine. since the engine can only work when a certain amount of gasoline is supplied, with too “poor” fuel, that is, overlapping the supply channel, the motor will stop;
  • too much fuel consumption, many exhaust gases. the result of incomplete combustion of the mixture. In this case, the fuel, on the contrary, is too much and the mixture is excessively dense.

STIHL, Makita, Husqvarna and others tuned with adjusting screws. Sometimes the reason for disrupting the work is a violation of fixation-due to vibration or damage to the protective cap. Such a breakdown can be found only by trying to turn the screw a little: if the fixation is not stiff, it is worth checking the setting.

Do.it.yourself carburetor adjustment

The setting of the module does not apply to the repair and the change of spare parts is not required. In this case, the armored complex of the carburetor of the lawn mower will not be needed.

  • L. is regulated first, as it is responsible for supplying fuel at low speeds;
  • H. he is responsible for supplying gasoline at high speeds, as well as for fuel consumption and temperature;
  • T. with it, the idle speed is debugged.

There are options, as a rule, this is a carburetor of a Chinese lawn mower, when only one screw remains for debugging on the case. to configure idle. This does not mean that the module is configured automatically. this means that even such a type of repair as debugging will be difficult to carry out. In the photo. adjusting the carburetor of the Chinese lawn mower.

  • The module tuning is carried out only with a heated engine: for this, the device is pre.included for 10 minutes. If the mowing head rotates at idle, then they begin to debugged immediately: turn the screw T counts the clock until the rotation stops.
  • Adjustment starts with a screw l. The screw turns to the right and to the left until it finds such a position in which the idle speed does not become maximum.
  • Then the screw is turned on ¼ turn against the watch. This will be his working position.
  • The idle stroke must be configured by turns against the sentry to increase the number of revolutions and the clock. to reduce. Its debugging consists in achieving such a regime in which a sufficient number of revolutions are performed before the rotation of the mowing head. In this case, the engine should operate steadily at different positions.
  • The position of the screw L is determined by the latter. at maximum speed the trimmer for grass should not work for more than 10 seconds. The throttle opens, the screw is closed clockwork, very slowly, until a decrease in the number of revolutions is established by ear.
  • Then also slowly the screw rotates against the sentry until the engine starts to work with failures. After which the screw is on the time, until the engine again works normally.

If there is a tanometer, and if the product is indicated in the product passport, coooreecration can be carried out more accurate, focusing not by ear, but on the testimony of the device.

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.

Features of regulation and regulation

To find out how to adjust the carburetor on a chainsaw, you need to learn how to distinguish three screws (some models have only one).

The screws l and h are similar only in appearance, but in fact they are different

  • “L” is used to install low speeds;
  • “H” must adjust the upper frequency of rotation;
  • “T” is required to adjust the velocity velocity (only one model is present on singlewood models).

Factory settings are optimal, and with the help of screws you can configure the engine in special situations (work is related to various climatic conditions).

The diagram shows the conclusions of the adjusting screws of the carburetor with a closed lid

A special tool is used to install a chainsaw

Adjustment is carried out only using screws l and n. To increase the speed of rotation, they rotate clockwise. Lower. counterclock-wise. Cooping sequence: l. H. T.

If you have doubts about regulation, it is better to consult with a specialist, since improper adjustment can damage the engine.

Adjustment of a trimmer carburetor for grass with one screw

Country construction and repairs are not done without using a chainsaw, as well as the care of the garden. Due to the malfunction of the tool, all the work may stand up, therefore, it is so fundamentally able to disassemble it without the help of others, look for problems and eliminate them. With sufficient experience and dexterity, even the adjustment of the gasopyle carburetor is likely. the procedure is not easy, or more precisely, jewelry. How to carry out adjustment procedures, we suggest for you now to disassemble.

Any repair event is not complete without knowing the basics of the mechanism of the mechanism. Understanding the constituent elements and the mechanism of work, it is easier to find the cause of the breakdown.

No matter what malfunction in the carburetor threatens to stop the motor

Carburetor is one of the main multifunctional parts of the motor, which serves to prepare and supply fuel consistency, consisting of certain proportions of fuel and air. How proportions are violated. the engine begins to “flounder”, or even stops working.

You can achieve the correct operation of the carburetor by examining its “filling”:

  • A pipe with a transverse damper to adjust the air flow.
  • Diffuser. narrowing in order to increase the air flow rate, is near the input hole of the fuel supply.
  • A sprayer from which fuel comes (fuel needle in the diagram).
  • A float chamber that regulates the level of fuel next to the entrance to the channel.

The scheme displays the interaction of fuel and air flow

Mechanism of operation: a stream of air in a diffuser spraying fuel, creating a mixture entering the cylinder. The not just the number of incoming fuel, the higher the speed of the motor. Carburetors of different models work according to one scheme.

Direct adjustment of the gasopyle carburetor is rarely required, often the tasks associated with the receipt of fuel, as it is also called the wear of the details. However, from time to time, “symptoms” indicate that it is necessary to specifically adjust the mechanism. Here are some signs:

  • If the engine has started, it stalls here. If necessary. in general it will not start. The reason lies in an excess of air and a lack of fuel.
  • Increasing fuel consumption, and as a result. many exhaust gases. This is due to the reverse process. oversaturation of consistency with fuel.

The prerequisites for the adjustment failure are also mechanical:

  • Due to severe vibration, the protective cap is damaged, as a result, three bolts remain to our client losing the established fixation.
  • Due to the wear of the piston part of the motor. In this case, setting up the carburetor of the chainsaw will help out only for a while, it is better to change the worn part.
  • Based on a blockage that appears due to poor fuel, scale or damage to the filter. The carburetor asks for a working version of disassembly, washing and adjusting.

If the chainsaw at one moment finished working, to clarify the circumstances, you need to disassemble it

The device of the carburetor of models of various brands is actually monotonous, so we take the Partner chainsaw as an example. Who carefully remove the element and put everything in order, so that later it is easier to collect.

Carburetors of chainsaws of various manufacturers, if they differ, are not principled

The upper cover is removed by unscrewing 3 bolts. Right behind it. foam rubber, component of the air filter.

The arrows indicate the bolts that need to be unscrewed to remove the lid

Then we remove the fuel hose, followed by the drive of the drive.

Carburetor adjustment

Before adjusting the carburetor, rinse the air filter. It is recommended to rinse every 10 hours of work. After that, you can start setting up. The photo shows the carburetor of the gasoline bush zerab-8406. The numbers indicate the adjusting screws that we will use.

Adjusting screws of the carburetor of a gasoline trimmer for the grass of the germino-8406

Run the gas cutting and wait until it heats up.

Fuel supply adjustment

Slowly start turning the fuel mixture adjustment screw until the engine starts to stall or stops if you do not have time to catch the moment. Then unscrew the screw for a quarter of turning if the engine does not stop, or half a turn, if it stalled. Launches the engine in the gloss state. Check, opening the throttle when the engine is gaining momentum. Continue unscrew the screw N. 1 quarter turnover until the engine begins to stably accelerate when gas supply. This will be the time of the most economical stable engine operation. In a gasoline trimmer for PRoraB-8406 grass, adjusting screws turn clockwise, unscrewed. counterclockwise, some other brands have a gasoline trimmer for grass on the contrary.

Cooper adjustment

Let’s start setting low speed. The screw limits the reverse movement of the accelerator lever: turning it, we increase the idle stroke, unscrewing. Reduce. Adjust the engine so that the engine confidently works at low speeds and even with a small throttle (for better starting), but so that the coil with the wire or the knife does not rotate, and that there is a sufficient supply of revolutions before they start to rotate. If the engine does not start, increase the idle speed further.

Limiting maximum revolutions

After adjusting the fuel mixture and low speed, check how the gasoline cutter engine will work at full speed. If necessary, limit the maximum speed to the required level using no. 3. Loosen the fixing nut and tighten the screw to reduce the maximum speed, or unscrew it to increase it. After adjustment, tighten the nut. Installation of the maximum speed is necessary to protect the engine of the trimmer for grass from overheating and in order to be able to use the castle of the ignition key to reduce the fatigue of the right hand.

In the future, an additional adjustment of the carburetor of the trimmer for grass may be required. For example, if the engine starts to work poorly when working with full load, weaken the screw 1 for another quarter turnover. If the launch is difficult, increase idle speed. Both weather conditions and the quality of the fuel mixture can affect the work of gasoline law mmores. Vibration can lead to the turn of the adjusting screws themselves.

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.

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.

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 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 ignition adjustment procedure

Setting the ignition system is simple and the same on different models of trimmers, whether it be STIHL FS55, Al-KO Sun 4125 or other gasoline cutter. First you need to remove the casing from the engine, after unscrewing the fastening, which fix it. This stage of dismantling may differ in different shield.brown models (described below). Next, you need to partially unscrew the mounts fixing the magneto with a screwdriver, and turn the flywheel so that the magnets are in the upper part.

To make an optimal gap between the coil and the magnet, you must use a special template. It is impractical to buy it for one.time use, so as an alternative you can use a business card or a small calendar, as well as a sheet of A4 paper, folded in four. A strip cut from a plastic bottle or other improvised materials is also suitable, has the necessary thickness. The optimal distance is usually indicated in the user guide. The selected item should be placed between the magnets and the coil.

Then the coil will be attracted to the flywheel with a magnetic field. Holding the magneto in this position, tighten the mounts that fix it, and then pull out the business card. After that, the flywheel must be turned several times to make sure that he did not touch the coil at all. The process has ended on the ignition on the shield. The process of setting up the trimmers ignition system can be studied in more detail on the Internet, where a lot is available on this topic.

Principle of operation

The order of injection and filtering of the fuel of the gas mowing engine is next.

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.

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.
