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.

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?

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.

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?
