How to adjust a trimmer for Delta BT grass. How the benzotrimer carburetor works and works
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.
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 to get a lawn mower: Action Procedure
To start a gasoline trimmer for grass, you must do the following:
- Close the air conditioning by shifting the lever.
- Turn on the ignition. for this you need to turn the key or handle to the appropriate position.
- If there is a manual fuel pump on a gasoline, then you need to press it 2-4 times until a combustible mixture appears inside the primer.
- Put the device on the ground. Click with a knee on the part where the engine is located, and slowly pull the starter handle until the moment when the resistance appears (the so.called hook). It is necessary to ensure that the gas mowing disk is currently not in contact with anything.
- Then, with a sharp movement, it is necessary to stretch the cord on yourself 3-5 times.
Когда триммер для травы заведён, заслонка открывается и фиксируется в среднем положении. Before operation, you should wait about five minutes. let the lawn mower will work at idle.
If you cannot start, you need to open the damper again. Otherwise, the candle will flood the fuel during subsequent movements of the cord. After that, you should 2-3 times start an open handbrake engine. If you can’t start it, you need to close the damper and try several more times.
The warmed motor is started elementary: its switch is put in the working position. Well, then the cord pulls to the start.
The common mistakes, which are often made by inexperienced owners, include the launch with unknown ignition or making jerks for starting more than five times when the damper is closed.
A few tips
It is impossible to launch in the room or in the same place where the equipment was refueled. The high concentration of exhaust gases that differ in toxicity has a negative effect on human health.
You can not smoke during the preparation or refueling of the combustible mixture. It is forbidden to carry out these actions near the open fire.
New equipment needs “running.in”. Do not sharply burn on gas. At first it is necessary to work, making short stops, so that all the elements, as they say, are pulled and greased enough.
Carburetor adjustment on a benzocos
DIY diagnostics and adjustment with your own hands can take only a few minutes.
Wash the filters before it (see. instructions). You can set the carburetor yourself with the help of three adjusting screws.
To do everything right, run the motor. Your actions are as follows.
- Find limit speed at idle. To do this, unscrew the screw l to the right, and then to the left. Turning step. a quarter of turning counterclockwise.
- Using the screw t, you can configure the idle speed of the motor: increasing when rotating the screw clockwise, decrease. on the contrary. The adjusted engine confidently works without load and without warming up. Heated. does not overestimate the moment.
- If you set up not a motorcycle, but a trimmer for grass, then the rotor of the screw t sets a greater margin of turnover per minute. For devices of both types, stable turns are set when choosing a mowing height with a knife (or fishing line).
- The last rotate the screw h. He sets the rate of supply of gasoline with air at maximum speed, engine power, motor heating temperature and fuel consumption.
To configure the motor from the screw h, do the following.
- Open the throttle and squeeze the gas at maximum speeds.
- Twist the screw h clockwise until the engine speeds are reduced.
- Twist slowly the same screw counterclockwise until the engine gives out unstable speeds.
- Take the screw back a little (clockwise) until the engine earns smoothly. It is important to catch this line.
The result of the exact adjustment is the complete combustion of fuel and the white-brownish color of the spark plug. The candle flooded with gasoline is much darker than the unbearable.
How to change the disk on the trimmer and for which motorcycle they are used
Trammers for grass differ in the method of engine operation. Electric and gasoline options are released. The latter. have a much more capacity of their competitors.
For miniature trimmers, plastic knives or light metal elements are traditionally used. For mowels of greater power, you can even use a winning disk for a trimmer for grass. But the restrictions affected not only the power of the devices.
The second principle is the mechanism: hard or gear. In the first. rotation is transmitted based on the shaft, and in the second. a steel cable. A flexible cable does not work with large discs, as it quickly becomes unusable. Therefore, for a flexible transmission, use a reel with a fishing line instead of knives. The type of device should be found out before the purchase, so as not to be with a quick breakdown.
Which knife for a trimmer for grass is better to choose? Review of possible options
Manufacturers produce several varieties of cutting elements for motorcycle. It all depends on the type of device. It is customary to distinguish between consumables:
What material for a trimmer knife is better
The purpose of the consumable determines the material: iron or plastic. The choice of one or another option is determined by several factors:
Important: metal mills are never installed on network braids. The power of the device is not enough for a full torque. Therefore, he appeared an alternative. plastic. Features of the design of the electric format motokos simply do not allow metal knives to work adequately:
Plastic blades are used only on devices with flexible hoses. Plastic copes with fine grass, dry areas and burdocks. If the wrong disk was accidentally installed, look further: how to change the disk to the reel on the trimmer.
Metal cutters. It is used for mowing thick, dense grass, small trees. The properties of a disc trimmer for grass allow you to install it in the fight against shrubs.
Technical and external characteristics that indicate that you need exactly an iron tip:
- straight bar, respectively. the length of the device itself increases;
- comfortable handles for control of a scythe;
- Setting a smooth turnover of the blade.
Tip: for mowing a large territory with different types of grass and shrubs, gasoline units are well suited. They need to install a metal disk with sharp knives on them.
How many blades should be
The form does not affect the efficiency of the blade as their total number. For example, for the future hay it is worth taking a mill for 6-8 blades. With an amount of 2-4, the grass is mowing “into the meat”, and you will not fall any drows. For young trees, blades with many small teeth are great (look in stores with winning elements. also a great option).
Labric mushroom knives are Natural in different ways: on one or both sides. Dumb or spent option increases fuel consumption and works inefficiently.
Important: try not to work with blades in areas with stones, brick. The only hit of the blade on the solid edge can break it can break it. Worse, if part of the pebble flies away in your direction. Be carefull!
How to change the nozzle for a trimmer for grass? The element should be selected on the basis of dimensions, material and design. Also focus on the format of work and the area that you will mow. The instructions from the tool will help you partially. Manufacturers indicate which knife what territory your equipment will process. Well, we go to how to put a knife on a trimmer for grass correctly.
Malfunctions and their elimination
Electric and gasoline trimmers have typical breakdowns and malfunctions. For devices running from an internal combustion engine, this is:
- problems in the carburetor;
- engine breakdown;
- problems with the fuel system;
- breakdown of the gearbox, starter, muffler;
- Air filter breakdown;
- Problems with ignition coil.
Electric units have specific breakdowns:
With simple problems, you can make a trimmer repair for grass with your own hands.
Why is a trimmer not starting for grass
The most common reason that the unit does not start is the use of poor.quality fuel. The choice of gas stamps below AI-92 can disable the lawnical mower. If high.quality fuel is used, you need to look for other reasons. To do this, carefully check all nodes and systems. The checks are subject to:
The device may not start after prolonged downtime. Before turning on a trimmer for grass, you need to study well the instructions for operation. The solution of many problems is indicated in it.
If it stalls when you press the gas
There are several reasons why a trimmer for grass stalls when gas is pressed:
- The first reason is the dumping of the carburetor.
- Fuel valve.
- Fur valve blockage.
- The weakening and sagging of the carburetor cable or sagging of the fuel intake hose.
So that the described problems with the lawn mower do not arise, you need to carefully monitor the condition of the device and its blocks. Timely cleaning, washing of the unit and spare parts allow you to increase its life.
The most difficult breakdown of the starter occurs when the rope is broken and winding it into the flywheel of the operating engine. As a result, the spring may burst and the pulley plunges. In this case, only a complete replacement of the spare part will help. This breakdown rarely occurs. often:
In this case, it is easy to fix the starter yourself. The manufacturer has prepared a step.by.step instruction for this.
Caring for the motorcade gearbox consists in the timely lubrication of the unit. The absence of one can lead to rapid wear of the gear and jamming of the gearbox module.
The main malfunctions of the trimmer gearbox for grass:
- severe heating of the gear component due to the use of low-quality lubrication or its absence;
- shaking of the shaft during the rotation of worn bearings;
- staggering or flowering from the bar of the gear ratio as a result of damage to the case;
- Lack of rotation of the output shaft with a knife due to wear on the teeth on the gears.
This happens due to the use of low-quality lubrication or its complete absence. Another reason for the failure of the gearbox is the operation of a trimmer for grass at the limit of its capabilities and the hit of foreign objects. To replace a faulty bearing, a gearbox is disassembled.
Features of the repair of electric models
Electric models of trimmers operating from the network have several main blocks:
Each electrimmer block has specific problems. In the mechanical part, they depend on the presence of a fishing line used as a cutting element. Reasons for the termination of work:
You can identify the problems of the electrical part of the electrocos using special tools:
To eliminate problems, a soldering lamp is needed.
- a malfunction of the power cable;
- problems with an outlet and fork;
- the failure of the control handle;
- combustion of the starter winding, engine replacement is required;
- Contact breaks can be corrected independently using a soldering lamp.
Setting up a carburetor of a lawn mower with three adjusting screws
Before starting work, you need to place the lawn mower on a flat stable surface. Remove the chain in the opposite direction. There are motorcycles with two and three adjusting screws. Two screws most often equip the tools produced in China. Consider the adjustment of the carburetor Motokos with three screws.
Setting up a carburetor of a lawn mower with three adjusting screws
Before proceeding with the adjustment of the carburetor of the lawn mower, you need to rinse the air filter. Cleaning is carried out with water with a detergent or soap, and if necessary, a new. Often in the poor work of the carburetor, scibberries are guilty. In order to prevent the filter, it is recommended to clean the filter after every 10 hours of operation of the tool. Do not forget to check the condition of the candle, if there is a dozen, you need to clean it. Candles are consumables and have their own resource. To ensure good operation of the engine of the lawn mower, candles periodically need to be changed. Next, we evaluate how well the carburetor is fixed to the cylinder-piston group. After the preparatory manipulations are completed, you need to start the motor. Let the engine work for 5-10 minutes. Then you need to identify how many adjusting screws on your tool.
There are the following adjusting screws on the gasoline trimmer:
Fuel supply adjustment
At first you need to slowly tighten the screw adjustment screw for the fuel mixture. You need to do this until the engine starts to stall or stalls. Following this, if the engine did not stop working, you need to turn the screw for a quarter of turnover, and if it stalled, then by half the turnover. Next, you should have a stalled engine. Then you need to open the throttle and see how the speed is gaining. Turn the screw for a quarter of turnover again. You need to scroll until the engine begins to confidently gain increased speeds during cuffing. This is the right time when the engine works most economically. There are times when adjusting this screw does not give anything. Often the reason is in the factory spring that is located on this screw. This does not happen to all the tools. And if the spring turned out to be defective, then replacing it will not be difficult. A suitable spring can be purchased at any construction store.
Following the adjustment of the fuel supply, we are accepting for the adjustment of the idle. To do this, you need to adjust the corresponding screw so that the engine works slightly accelerated at small speeds. But it is necessary to trace, for the immobility of the reel with fishing line and knives. Before the start of their movement, several revolutions should remain in stock. The movement of the coil and knives can subsequently lead to the rapid wear of the clutch. Having noticed that the engine starts poorly, you need to increase the number of revolutions at idle. With an increase in revolutions, the fuel mixture is saturated with air, which leads to power loss.
The main signs of the proper idle work:
- Revolutions for a trimmer head;
- Uninterrupted operation of the engine even when the position changes (sharp rise or descent of the knife);
- Calm operation of the engine at a cold move;
- Lack of increased speed of hot engine.
Maximum speed adjustment
Further, for the full tuning of the carburetor of the lawn mower, it is necessary to adjust the maximum speed. It will not be superfluous to look into the instrument operating manual and see the maximum speed value. This amount will help to determine the tachometer most accurately. If such a device was not at hand, we set up by ear. Barely determining the maximum speed of revolutions by ear, we begin adjustment. A screw for limiting maximum revolutions will help in this matter. Control the engine operation at maximum speed. If necessary, reduce speed, weaken the fixing nut and unscrew the screw. If the turnover is too large, then you will need to screw the screw. These actions must be done in order to protect the engine from overheating. Scroll the screw until the clear even operation of the engine is established.
After the work done, if everything is done correctly, the stable work of the tool is provided.
Understand this by the following signs:
How to understand that the carburetor of the lawn mower needs to be adjusted
The following signs may indicate this:
- Difficult launch of the motor, weak speed set.
- Increased fuel consumption.
- The engine works unstable, the speed is often jumping.
- There is a large amount of exhaust gases.
Find out whether the carburetor is correctly adjusted, checking the spark plug will help. First we release it from the casing, disconnect the contacts from the igniter.
Clean the candle nest with a device that pumps the air. For this purpose, a compressor with a small tube is perfect. Using a dynamometric key, we remove the candle.
After pour the sparkle with the spark plug for flushing the thread into the nest, unscrew the candle to the end after a short period of time. If the electrodes are black, then this is a dozen that is associated with poor carburetor adjustment. If she is a brick shade, then everything should be in order with a gas station.
After a long period of downtime, the tool also needs to be adjusted. For example, after winter.
It is also recommended to set up a setting when changing the composition of the fuel mixture: oil or gasoline.
How to adjust the carburetor of the lawn mower with your own hands
- 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.
