  If your Troy-Bilt Trimmer engine won't start, several issues could be the cause. First, ensure the fuel tank isn't empty; if it is, fill it with properly-mixed fuel. If the engine is flooded, press the throttle lockout, squeeze the throttle control, and pull the starter rope until the engine starts. Old or improperly mixed fuel can also be a culprit, so drain the tank and add fresh fuel. A fouled spark plug should be replaced. Also, make sure you have pressed the primer bulb 10 times. Finally, refer to the Starting Instructions in the Starting and Stopping section to ensure the choke lever was flipped.

  If your Troy-Bilt Trimmer engine will not accelerate, it might be due to a few reasons. The fuel could be old or improperly mixed; in this case, drain the fuel tank and add fresh, properly-mixed fuel. Also, the cutting head (or blade) might be bound with grass; stop the engine and clean it. A dirty air filter can also prevent acceleration, so consider cleaning or replacing it.
