Why does my Efco Brush Cutter engine not reach full speed and emit smoke?

If your Efco Brush Cutter engine doesn't reach full speed or emits excessive smoke, first, ensure you are using fresh fuel and the correct 2-cycle oil mix. Next, check and clean the air filter. If the issue persists, it may be necessary to have a servicing dealer adjust the carburetor.
