Solution 2:
Carburetor
The carburetor might be clogged. 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 evapor...ate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

Solution 4:
Recoil Starter
The recoil starter assembly engages the crankshaft to turn over the engine. If the recoil starter assembly is defective, the engine won't start. Remove the starter assembly and inspect it to determine... if it is working properly. When you pull the starter rope, tabs extending from the pulley and cam should grab the hub on the engine, causing the engine to turn. When you release the rope, the tabs should retract and the rope should rewind back on the pulley. If the recoil starter assembly is not working properly, replace it.

Rewind Pulley and Spring
The rewind spring might be broken. When the starter rope is pulled and released, the rewind spring recoils the starter rope onto the rewind pulley. If the rewind spring is broken, the rope won’t be ab...le to recoil onto the pulley. As a result, the engine won’t start. If the rewind spring is broken, replace it. Many rewind springs can be replaced individually, but it may be easier to replace the whole rewind pulley and spring assembly.
