Why won't my Ryobi RBC31SESO Trimmer start?
- A
  Amy GordonAug 1, 2025
  There are several reasons why your Ryobi Trimmer might not be starting: * **No spark:** The spark plug could be damaged. Check it for dirt and cracks, and replace it if necessary. * **No fuel:** Push the primer bulb until it's full of fuel. If it doesn't fill, the primary fuel delivery system may be blocked. * **Engine is flooded:** Remove the spark plug, turn the trimmer so the spark plug hole faces the ground, rotate the choke dial to the “ ” position, and pull the starter cord 10 to 15 times to clear excess fuel.

  If your Ryobi Trimmer starts but won't accelerate, it might be due to old fuel. Make sure you're using fresh fuel mixed with the recommended oil. Fuel older than 30 days can prevent the trimmer from starting or accelerating properly.
