Why does my trimmer dies when I give it gas?
One reason why one of these trimmers may die at full throttle is that too much oil is in the gas, which causes poor combustion. Improper operation, including overuse of the choke, can also be responsible. Poor combustion produces carbon deposits that foul the spark plug and exhaust port, making the problem worse.
Why does my trimmer keep shutting off?
A clogged carburetor is most commonly caused by leaving fuel in the string trimmer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
Why does my trimmer only run on full choke?
When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.
Why does my strimmer cuts out when revved?

Why does my 2 cycle engine stall when I give it gas?
One of the possible reasons why your two stroke engine is stalling when revved is because of a clogged filter.

How do you clean a fuel filter strimmer?

Why does my 2 stroke engine only run on choke?
If your engine only runs when it’s half choked, there’s a problem. When a two-stroke only runs on half choke it is usually the result of a dirty fuel cap, a leaking gasket, a clogged carburetor, or a gunky passageway. You can fix these problems by cleaning the carburetor, removing the fuel, and adding new gas.
Why does my Weedeater only run on half choke?
A weed eater only runs on half choke when there is dirt or a clog in the carburetor or gas cap that needs to be cleaned. A dirty carburetor will restrict fuel and airflow. When the check valve in the gas cap is clogged, the fuel creates a vacuum and gets vapor locked. The choke allows air inside.
Do you have to choke engine to keep running?
An engine that requires the choking ( partial or full ) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment. Both the manual choke system and the manual primer system engines may experience this similar symptom of running only when the fuel mixture is enriched.

When I open the throttle the engine dies?
A clogged air filter will starve the engine of oxygen, causing the engine to die at full throttle. The engine may idle normally, but at higher RPMs it may not get enough fuel, causing the engine to stall. To inspect or replace the fuel filter, follow the fuel line from the tank to the carburetor and locate the filter.
What causes engine bogging?
The problem of an engine bogging out is commonly caused by inefficiency of fuel or air flow or ignition to the carburetor. If the air filter is clogged or has a lot of dirt in it, it could be bogging down the engine. Clean the air filter and see if the problem goes away.
