If your Ryobi Trimmer engine doesn't reach full speed and emits excessive smoke, it could be due to: 1. Incorrect fuel mixture: Use fresh fuel and the correct 2-stroke oil mix. 2. Dirty air filter: Clean the air filter according to the instructions in the Maintenance section. 3. Dirty spark arrestor screen: Contact an authorized service dealer.
