How to fix Ryobi RLT254CDSO if engine will not start?
- R
  Robert JohnsonAug 19, 2025
  If your Ryobi Trimmer engine won't start, there could be several reasons. First, the spark plug might be damaged, so remove it and check for dirt or cracks, and replace it if needed. Second, there might be no fuel, in which case you should push the primer bulb until it's full. If it doesn't fill, the primary fuel delivery system may be blocked. Finally, the engine could be flooded. To fix this, remove the spark plug, turn the trimmer so the spark plug hole faces the ground, rotate the choke dial to the indicated position, and pull the starter cord 10 to 15 times.

  If your Ryobi Trimmer engine isn't reaching full speed and is emitting excessive smoke, start by checking the lubricant fuel mixture. Ensure you're using fresh fuel and the correct 2-stroke lubricant mix. Also, a dirty air filter can cause this issue, so clean the air filter.

  Eric HarrisonAug 27, 2025
  If the line on your Ryobi Trimmer won't advance, it could be due to a few reasons. The line might be welded to itself; try pulling the lines while alternately pressing down on and releasing the bump head. Alternatively, there might not be enough line on the spool, so install more line. Also, make sure the engine speed isn't too slow; try advancing the line at full throttle.

  Lindsay CalderonSep 5, 2025
  If your Ryobi Trimmer engine starts but won't accelerate, the issue might be old fuel. Make sure you're using fresh fuel mixed with the recommended oil, as fuel older than 30 days can prevent the engine from starting properly. Also, the engine may need about three minutes to warm up completely.
