Why Ryobi Trimmer engine will not start?
- C
  Chad DavisJul 31, 2025
  If the Ryobi Trimmer engine won't start, there might be several reasons: * **No spark:** Try cleaning or replacing the spark plug and resetting the spark plug gap. * **No fuel:** 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 service dealer. * **Engine is flooded:** Set the start lever to the START position, squeeze the trigger, and repeatedly pull the rope until the engine starts and runs. Keep in mind that depending on how flooded the engine is, you may need to pull the rope many times.

  If the Ryobi Trimmer engine starts, runs, and accelerates but won't idle, the idle speed screw on the carburetor likely needs adjustment. Turn the idle speed screw clockwise to increase the idle.

Why is the spool retainer hard to turn on Ryobi RY30570 Trimmer?
- A
  Angela CollinsAug 25, 2025
  If the spool retainer on your Ryobi Trimmer is hard to turn, it might be because: * **Dirty or damaged screw threads:** Clean the threads and lubricate them with grease. If this doesn't help, replace the spool retainer. * **Cutting tall grass at ground level:** Cut tall grass from the top down to prevent wrapping. * **Operating at part throttle:** Operate the trimmer at full throttle.
