  If your Ryobi Trimmer engine won't start, there are several potential causes. First, check for spark by removing the spark plug, reattaching the cap, and laying it on the metal cylinder. Pull the starter rope and look for a spark at the plug tip. If there's no spark, try a new spark plug. Second, ensure the primer bulb fills with fuel when pushed. If it doesn't, the fuel delivery system may be blocked, and you should contact a servicing dealer. If the bulb fills, the engine might be flooded. Set the start lever to the START position, squeeze the trigger, and repeatedly pull the rope until the engine starts. Note that this may require numerous pulls. Also, if the starter rope pulls harder than when new, contact a servicing dealer.

Why does my Ryobi RLT30CDNB Trimmer engine start, run, and accelerate but will not idle?

  If your Ryobi Trimmer 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 speed.

What to do if the line will not advance on my Ryobi RLT30CDNB Trimmer?
- J
  John RayAug 10, 2025
  If the line on your Ryobi Trimmer won't advance, consider these possibilities: The line may be welded to itself, in which case you should lubricate it with silicone spray. There might not be enough line on the spool, so install more line. The line could be worn too short, in which case you should pull the lines while alternately pressing down on and releasing the bump head. The line could also be tangled on the spool, so remove the line from the spool and rewind it. Finally, the engine speed may be too slow, so advance the line at full throttle.

  If your Ryobi Trimmer engine doesn't reach full speed and emits excessive smoke, check the lubricant fuel mixture and use fresh fuel and the correct 2-stroke lubricant mix. Also, the air filter might be dirty, so clean the air filter.

  If your Ryobi Trimmer engine starts but won't accelerate, allow the engine to completely warm up for approximately three minutes. If it still does not accelerate after this time, contact a servicing dealer.

What causes grass to wrap around the shaft housing and bump head of my Ryobi Trimmer?
- K
  Krystal DavisAug 26, 2025
  Grass wrapping around the shaft housing and bump head of your Ryobi Trimmer can be caused by cutting tall grass at ground level, so cut tall grass from the top down. It can also happen if you're operating the trimmer at part throttle, so operate the trimmer at full throttle.
