What to do if Ryobi RHT2660RN engine does not reach full speed and emits excessive smoke?
- VVincent JordanAug 7, 2025
If your Ryobi Trimmer engine isn't reaching full speed and is emitting excessive smoke, it could be due to: * Incorrect lubricant fuel mixture. Use fresh fuel and the correct 2-stroke lubricant mix. * A dirty air filter. Clean the air filter. * A dirty spark arrestor screen. In this case, contact a servicing dealer.
