Trimmer stalls at high revs cause petrol
the lawn mower stalls at high engine speeds
During operation, a situation arises when, when you press the fuel mixture supply button, the speed of the unit does not begin to increase, but to decrease. A malfunction of this nature can be caused by:
Fuel hoses for lawn mowers with filter
- etching atmospheric air into the combustion chamber;
- problems with the circulation of the fuel mixture;
- clogging of the breather in the fuel tank cap (cleaning the hole with a fine sewing needle);
- incorrect carburetor adjustment.
When air is leaking during the operation of the internal combustion engine, it is necessary to check the tightness of the connection of the pipes and the integrity of the gaskets in the CPG. The problem with the circulation of the fuel mixture can be solved by removing blockages in the fuel pipes leading to the carburetor. If a vacuum occurs in the tank and the fuel mixture does not flow to the carburetor, it is enough to clean the breather with a thin needle and blow it with air.

With a similar problem, you should pay attention to the fuel valve, which, when clogged, ceases to pass the fuel mixture normally. The solution to this problem is to mitigate it with a suitable tool. In addition, the problem with the circulation of the fuel mixture may lie in the contamination of the valve. To do this, it is enough to blow it with a stream of compressed air.
Trimmer stalls: causes and troubleshooting
The lawn mower is a mobile, high-performance tool for beautifying home gardens and surrounding areas. With prolonged operation, due to wear of parts or manufacturing defects, malfunctions occur, which lead to the fact that the trimmer stalls or does not start. Since this tool is a rather complex mechanism, there may be several reasons why the lawn mower stalls.
Why does the trimmer stall
There are two main ways to troubleshoot problems: transferring the braid to a specialized center or solving the issue with your own hands. The first option is suitable for those who are ready to pay a “tidy” sum to restore the unit’s performance, and the second for those who have basic locksmith skills and can independently figure out the causes of breakdowns and ways to eliminate them.
- mechanical damage to the internal combustion engine crankcase, malfunctions of the cylinder-piston group (CPG);
- breakdowns associated with the supply of the fuel mixture (air filter, carburetor);
- malfunctions due to damaged tubes, hoses, cables or ignition circuit.

The reason why the trimmer starts and stalls
Trimmer Starts And Stalls Immediately Causes
In recent years, the gasoline trimmer has gained textbook status as one of the main tools in the arsenal of summer residents. And such actions are logical, because a motorized scythe allows you to quickly put your personal plot in order. But it happens that the trimmer does not start on hot and cool. In such situations, it is necessary to establish the cause of the malfunction without the help of others. Next, let’s figure out what to do if the trimmer won’t start. The premises that mostly lead to such troubles will be examined further.
Where to start diagnosing defects if the trimmer won’t start? In situations where the tool stalls immediately after starting, it is worth looking at the following units of the unit:
Specifically, the breakdown of the above locations for the most part leads to the fact that the trimmer does not start well. It is necessary to consider how to remove such problems.
Top Reasons Chainsaw Starts, Then Stalls — Chainsaw Troubleshooting
Let’s say your trimmer won’t start. Then the beginning of everything is to check whether there is enough fuel in the tank, to additionally evaluate the quality of the fuel consistency. The motorized unit should only be refueled with high quality gasoline. It is recommended to use fuel, the grade of which is not lower than AI-95. Filling the trimmer with fuel of unknown origin not purchased at a gas station can lead to frequent malfunctions of the tool. This causes a breakdown of the cylinder-piston accounting system. Repairs under these circumstances often exceed the price of the device itself.
Why won’t the petrol trimmer start? Incorrect preparation of the fuel consistency, which consists of oil and gasoline, can also lead to this. The proportions in which the designated components are connected are indicated by the manufacturers in the trimmer instruction manual. It is highly discouraged to prepare a fuel mixture in large volumes, in other words, for the future. Indeed, with long-term savings, there is a loss of the determining parameters of the substance. If the trimmer does not start, it is worth draining the old fuel and using a freshly prepared fuel consistency.
Does the engine stall immediately after starting? why is this happening
Another common prerequisite for not starting the trimmer is the presence of a blockage in the filter area. To confirm the hypothesis, it is enough to dismantle the designated unit and test the start-up of the unit without it. If the trimmer engine starts, most likely you will have to create a change of the air filter or, at least, perform a painstaking purge of the old one. If there is abundant contamination on the filter element, use the latest mesh. When resorting to similar actions, it is not recommended to leave the absorbing tube completely without a filter. After all, haste in our version leads to the need to repair the entire piston group of the engine unit.
Often the engine of branded trim models stalls when the breather is clogged. The main task of the designated component is to equalize the pressure in the fuel tank. For which the design of the contamination of the unit is intended, a vacuum appears here, which greatly complicates the supply of fuel. The fault can be removed by cleaning the breather with an ordinary sewing needle.
Trimmer ON COLD does not start well, what to do?
What to do if the used fuel mixture is in perfect order, alas, as before, the petrol trimmer does not start? The prerequisites for the failure of the mechanism are variations to be found in the excessive moisture of the candle channel. To diagnose and eliminate the difficulty, you need to do the following:
- Remove the candle. Wipe it painstakingly and dry it further.
- Drain off excess fuel in the chamber through the corresponding plug hole.
- Clean an old candle if there is carbon deposits on its surface. The use of an ordinary ladies’ nail file or a file will allow you to cope with the task.
- To install the element in the area, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the gap.
- Assemble the multifunctional unit back.
- Try to start the trimmer.
It is recommended to dry the candle channel at a minimum for half an hour. But do not resort to calcining its parts. After all, heating the spark plug leads to its final damage. What to do if the service of the multifunctional unit was carried out according to the above tips, but the trimmer does not start, of course there is a spark with all this? Here it is worth treating the threaded connection with gasoline. The latter does not need to be abundantly impregnated with fuel. It is only slightly moisturized. Such actions should be taken to ensure ignition. After all, no matter how strong a spark is given by a candle, in a completely dry chamber there simply will not be anything to ignite.
Even if the trimmer does not start here, it is worth assessing the quality of the contact between the high-voltage wire and the candle. For which the design of the absence of a spark is intended (if there is a reliable connection between the designated elements), for sure, the discrepancy is caused by a breakdown of the ignition unit. In this situation, you will have to turn to the services of wizards who will reinstall the node.
