petrol grass trimmer you give gas and stalls

If stalled after gas supply

Owners of gasoline braids quite often mention that the lawn mower stalls when you press the gas. Typically, such a breakdown occurs due to a malfunction in the carburetor. Failure in its operation can occur due to prolonged storage, use in difficult conditions, significant overload of the motor. Vibrating movements of the device during operation will become a symptom of such a breakdown.

On a note! Users familiar with car carburetor repair can try rebuilding this important grass trimmer unit on their own using the instruction manual. Otherwise, the right decision would be to contact the service center representatives for help.

Sometimes the grass trimmer stalls when you throttle because the fuel valve is clogged. This interferes with the supply of gasoline. To fix the problem, it is enough to loosen the valves. This will restore the normal fuel supply to the carburetor.

Another possible reason the mower stalls when gas is applied is a dirty breather (check valve). This part prevents the formation of a vacuum in the gas tank. If it is clogged, air does not flow, which means that fuel does not go to the carburetor. To fix the problem, you need to clean this element.

If stalled under load

Sometimes the grass trimmer stalls under load because it cannot gain momentum. This means that the cable, which is taut in the carburetor, is loose and slack. If you have experience in repairing this unit, the cable should be tightened.

Weedeater starts but dies. Easy quick fix.

Another cause of the malfunction is that the fuel intake hose is too tight. Under load, it stretches even more, as a result of which cracks are formed, as a result, the part deteriorates. To eliminate the breakdown, you will need to replace this element.

If stalled without gaining momentum

If the grass trimmer does not pick up and shuts down, there could be several reasons. The most common culprit is a clogged air filter. It must be pulled out and cleaned, if necessary, replaced.

On a note! The grass trimmer could stall without gaining speed due to a carburetor malfunction. The unit for repair or replacement must be taken to the service center.

Another possible malfunction is related to the mechanics of the motor drive. This part of the grass trimmer must be thoroughly cleaned and the inner cables must be lubricated.

You also need to make sure that the cable in the carburetor has not slept. Before using the grass trimmer for the first time, check this structural element to ensure that it is firmly and not taut. Otherwise, the cable may crack, resulting in costly repairs.

If stalled at high speeds

If the carburetor stalls at high speeds, this means that at idle and low speeds, the incoming fuel is enough for it, but not enough to work at high speeds. Then it is necessary to check the serviceability of the following units of the grass trimmer.

  • Fuel hose. may have been damaged by cracking. In this case, you need to replace the part. Or maybe you just need to tighten the clamps.
  • The filter mesh between the carburetor and the gasoline supply hose. it could be clogged. In this situation, it is necessary to clean the part.
  • The valve located on the gas tank cap. it could get stuck or clogged with debris. Cleaning is also needed.
  • Carburetor. it may be misaligned as a result of constant vibration. This is usually the case for cheap Chinese parts. To fix the problem, you need to configure according to the instructions. In some cases, it is enough just to loosen the tightening of the carburetor body. If the adjustment fails, you need to install a new element.
  • Additionally, you should check the air filter. It may need to be rinsed and cleaned or replaced with a new one, as it could become clogged with dirt and grass particles when the equipment is tilted, when the user mowed in hard-to-reach places.

If stalled during idle operation

If the mower stalls while idling, there could be several factors.

  • First you need to check the prepared fuel solution when it comes to a four-stroke trimmer that runs on a gasoline-oil mixture. There is a possibility that it was made incorrectly. the proportions are not maintained. Because of this, the gearbox heats up, and the revolutions on the drum decrease.
  • Another likely cause is a clogged element such as the throttle valve, air filter, or carburetor. The specified parts need to be cleaned.
  • Another possible factor is misalignment or misalignment of the carburetor. You need to re-configure according to the instructions.
  • Observe this problem mono even when the air damper is opened. In this situation, the lack of fuel for the grass trimmer is caused by the air flow.

If the device does not have enough fuel, it works properly at high speeds or when they increase, but stalls at idle. If the carburetor is at the root of the problem, the mower will shut off during cold start and hot start.

If stalled after launch

If the equipment starts and stalls immediately after starting, this indicates an incorrect setting or misalignment of the device. As a result, fuel does not flow to the engine evenly, resulting in significant vibration and disengagement of the grass trimmer. To fix the breakdown, it is necessary to reconfigure the device according to the user’s manual.

Another likely problem is a clogged gasoline supply valve. It needs to be cleaned.

On a note! If the grass trimmer starts but stalls right away, it could also mean that fuel is having difficulty flowing to the carburetor. Weakening the valve will help to eliminate the problem. this will ensure uniform and free circulation of fuel in the device.

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

If stalled when heated

the mower often stalls when heated. It looks like this. the tool starts up, works “jerky” (not smoothly) and quickly stalls. This situation occurs due to fuel boiling in the carburetor or an incorrectly selected damper, which should not be disk, but rotary. In the latter case, if an error is found, the part must be replaced.

Damaged ignition wiring or a defective coil can cause the grass trimmer to heat up. A broken knot will need to be replaced with a new one.

What to do if the grass trimmer stalls when you press the gas?

So why does the grass trimmer stall when you step on the gas? There can be several reasons for this problem.

  • The carburetor is out of alignment after an unsuccessful wintering or after too much use of the brushcutter. The petrol grass trimmer runs on an air / fuel mixture prepared by the carburetor. If incorrectly adjusted, this mechanism prepares a lean mixture, which is not able to provide the engine with a sufficiently high speed. You can understand the problem with the carburetor by the characteristic vibrations of the lawn mower.
  • You can tell if the fuel filter is clogged by the grass trimmer starting and stalling. In other words, there is enough fuel flow to start the brushcutter, but not enough to keep the engine running. It may be possible to solve the problem by loosening the valves on the filter. If not, you should wash the filter in solvents and blow it out with compressed air. If after that the problem is not solved, then you should purchase a new fuel filter.
  • If the engine stalls at speeds close to maximum, then there may be a problem with the breather, which regulates air access to the gas tank. When fuel is consumed too quickly, which is typical when you give gas, a rarefied pressure is formed in the gas tank, due to which the flow of fuel into the engine is reduced.
  • The engine stalls when the choke is opened. The problem, again, is associated with the carburetor, which, due to excess air, prepares a lean air-fuel mixture, which is not capable of ensuring engine operation.

What to do if the mower starts and stalls?

Now we will consider all the above described problems in more detail.

In principle, there can be a huge number of reasons why the engine of a brushcutter stops working when you press the gas. We will only consider here the most common.

Perhaps the air damper is just clogged. And to eliminate the problem that has arisen, it will be enough just to clean the air damper. Also, the engine stalls due to a clogged air filter. To clean it, the filter should first be washed in a solvent, and then blown out with a stream of compressed air.

A similar procedure should be carried out with a clogged fuel filter, which prevents the flow of fuel in the proper volume when increasing engine speed.

The engine can also stall for other reasons. Firstly, the spacer located between the cylinder and the carburetor worn out, and secondly, the crankshaft oil seals began to suck in air.

We have already pointed out that in this case the problem is in the carburetor. Due to the increased temperatures, gasoline begins to boil in it, due to which the air-fuel mixture ceases to form or its quality is critically reduced.

In addition, this problem can arise due to the fact that the carburetor is equipped with a rotary rather than a disc valve. If the problem has become chronic, then it should be solved radically. by buying a new carburetor with a disc damper.

Most likely, access to the fuel tank is difficult or completely absent, due to which a low pressure zone forms in it, due to which the engine stops receiving fuel in the required amount and because of this it stops working.

The engine at idle speed can stall for the following reasons:

he got up and began to prepare a not quite normal gasoline solution, which is why the revolutions on the drum began to drop;

  • Clogged carburetor;
  • The carburetor is incorrectly adjusted;
  • The throttle valve is dirty;
  • The throttle is open, which causes too much air to enter the carburetor, which makes the air-fuel mixture lean;
  • Clogged air filter.
  • Why the lawn mower stalls?

    In this article we will look at the problem, why the lawn mower stalls and how to deal with this problem.

    Even a very good brushcutter can have starting problems. For example, it starts up and stalls. Most likely, this indicates problems with the filters. air or fuel. If it stalls at idle, then, most likely, the brushcutter has problems with the carburetor, which overheats too quickly and can no longer cope with the formation of a high-quality air-fuel mixture.

    Trimmer starts and dies. Quick fix.

    If the grass trimmer stalls when you press the gas, i.e. when the engine starts to run at high rpm, then this indicates a problem with the carburetor or fuel filter.

    Problems with brushcutters with an air filter will be indicated by the fact that it stops working when the air damper is opened.

    the lawn mower stalls on hot? There is a solution!

    the mower stalls when hot. this means that there is already some fuel in the engine to start the engine, but after 5-10 minutes of operation, it stops working. This behavior of the engine indicates problems with the fuel filter.

    There are two solutions. preventive and radical. Preventive is to try to clean it, which will consist in cleaning the contamination with a solvent, and then blowing the filter with a jet of compressed air.

    But in case of severe pollution, you can fix the breakdown only by applying a radical solution. this is the purchase of a new fuel filter.
