Why does my Ryobi RBC254FSBSN engine not reach full speed and emit excessive smoke?

If your Ryobi Trimmer engine doesn't reach full speed and emits excessive smoke, check the following: * Oil fuel mixture: Use fresh fuel and the correct synthetic 2-stroke oil mix. * Air filter: Clean the air filter.
