Why Ryobi Trimmer engine will not start?
- J
  Jacqueline WallaceJul 26, 2025
  If your Ryobi Trimmer engine won't start, it could be due to no spark, no fuel, or a flooded engine. Try cleaning or replacing the spark plug and resetting the spark plug gap. Push the primer bulb until it's full of fuel; if it doesn't fill, the primary fuel delivery system might be blocked, and you should contact a servicing dealer. If the primer bulb fills, the engine may be flooded. Pull the starter three times with the choke lever at 'RUN'. If it still doesn't start, move the choke lever to 'START' and repeat the normal starting procedure. If it still fails, repeat the procedure with a new spark plug and if the problem persists, contact a servicing dealer.

  If your Ryobi Trimmer engine doesn't reach full speed and emits excessive smoke, check the lubricant fuel mixture, and inspect the air filter and spark arrestor screens for dirt. Use fresh fuel and the correct 2-cycle lubricant mix. Clean the air filter screen, and if the issue continues, contact a servicing dealer.

  If the Ryobi Trimmer engine starts, runs, and accelerates but will not idle, the idle speed screw on the carburetor may need adjustment. Turn the idle speed screw clockwise to increase the idle speed. The blades should not move at idle.
