The lawn mower stalls when you press the gas, how to fix a breakdown

Likewise, when the throttle is pressed, the tool stalls because the drive is clogged. The following option is also possible: the fuel is not supplied in full, so you need to check or replace the fuel filter. Other possible reasons for a stalled brushcutter when you give gas are:

  • Crankshaft oil seals suck in air;
  • A spacer that is located between the carburetor and the cylinder in a “problem” situation;

To all these reasons for which the mechanism stalls when gas is added, we will add some useful recommendations for handling the brushcutter. First of all, before starting work with any technique, you need to read the instructions. In this case, the consistency of gasoline and oil plays an important role, it is competently prepared by you, and also not to overheat the unit, and not to leave gasoline for the winter when you simply will not use the car.

The well-coordinated work of all its components plays an important role in the full-fledged work of any tool. And if in one it is a line for a brushcutter, then in the other there is a piston or a carburetor. Owners of brushcutters who want to use their tool at full capacity need to understand that under a load for which the capabilities of the machine are not designed, the entire mechanism or its individual parts can simply break. Therefore, only competent and moderate operation presupposes long-term efficient operation of any gasoline-powered tool.

Causes of malfunction and their elimination

To most accurately determine the cause of a malfunction of any brand of grass trimmer (for example, Echo) and find out the possibility of its elimination, it is necessary to establish at what action the device stalls. The engine can be turned off both at idle and at high speeds, heating up under load or immediately after starting, etc.

If it stalled when opening the damper

If the equipment works properly at idle, but stalls when the air damper is opened, this indicates the penetration of air into the system through cracks in the fuel supply hose or damaged oil seals. In order to fix the breakage and adjust the operation of the tool without sucking air from the atmosphere, it is necessary to replace the damaged parts.

Another possible cause of a breakdown is a malfunction of the carburetor dosage system. To fix this problem, it is better to contact the professionals.

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.

the lawn mower stalls when you press the gas cause

Those who have lawns on their backyard know that a grass trimmer is quite a useful thing that will help you quickly and efficiently tidy the lawn or clear weeds from overgrown areas.

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 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.

Immediately after wound up

The unit may stall immediately after starting if the carburetor is misaligned or incorrectly adjusted. this causes an uneven fuel supply. The result is that the device vibrates distinctly. To troubleshoot the carburetor, readjust, following the instructions for the mechanism.

Also, the engine stops when the fuel supply valve becomes clogged. In such cases, it is sufficient to simply clean it. If the mower started up at first, but then immediately stalled, then it is possible that the fuel enters the carburetor unit with some difficulty. The weakening of the valve helps to resolve the issue, which ensures free circulation of the mixture in the system.

A stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks) that takes the fuel. In this case, add more revolutions to the drive in order to quickly expel air bubbles from the system.

  • Loosening and drooping of the cable in the carburetor. The fuel hose may also be stretched to the point of rupture due to significant stress.
