Why does my Ryobi Trimmer engine emit excessive smoke and not reach full speed?

If your Ryobi Trimmer's engine isn't reaching full speed and is emitting excessive smoke, make sure you are using fresh fuel and the correct 2-stroke oil mix. Also, clean the air filter according to the instructions in the Maintenance section. If problems persist, contact a service dealer.
