  Patrick LongJul 30, 2025
  Several factors can prevent your Troy-Bilt Trimmer engine from starting. It could be due to an empty fuel tank, which requires filling with new fuel. Insufficient priming might be the issue; try fully and slowly pressing the primer bulb 10 times. Old fuel can also be a culprit, necessitating draining the tank and adding fresh fuel. A fouled spark plug may need cleaning or replacement, and a plugged spark arrestor might require similar attention. Finally, check the Cold Weather Start Lever position relative to the outside temperature: ensure it's OPEN/RUN above 40°F and CLOSED/START below 40°F, following starting instructions accordingly.

  If the cutting attachment on your Troy-Bilt Trimmer isn't advancing, several issues could be at fault. The cutting attachment might be bound with grass, in which case you should stop the engine and clean it. Other potential causes include the cutting attachment being out of line (refill with new line), an inner reel bound up (replace the inner reel), a dirty cutting head (clean inner reel and outer spool), line welded (disassemble, remove the welded section, and rewind), line twisted when refilled (disassemble and rewind the line), or not enough line exposed (push the bump knob and pull out line until 4 inches (102 mm) of line is outside of the cutting attachment).
