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.
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.
Remove the air filter and spray carburetor cleaner into the intake. Let it sit for several minutes to help loosen and dissolve varnish. Replace the filter and try starting the trimmer. If this doesn`t solve the problem, consider disassembling the carburetor to give it a more thorough cleaning.
If your bike is only running with the choke on, it`s probably because it`s running too lean. This can be caused by a few different things: All internal combustion engines need three things to run: fuel, air, and spark. If any of these are missing or not working properly, the engine won`t run.

The air filter may be clogged. If the air filter is clogged, the engine will get too much fuel and not enough air. As a result, the engine may not start. If the air filter is clogged, replace it.
The air filter or exhaust port may be blocked. The trimmer may need lubrication and cooling fins or air passages may be blocked. A cordless trimmer`s battery or charger may be faulty.
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the edger may stall or run roughly. To unclog the spark arrestor, remove it and clean it with a wire brush. You can also replace the spark arrestor.
