Why does my Efco Brush Cutter engine not reach full speed and/or emit excessive smoke?
If your Efco Brush Cutter engine doesn't reach full speed or emits excessive smoke, first, ensure you're using the correct 2-cycle oil mix with fresh fuel. Second, clean the air filter according to the Maintenance-Air Filter Section instructions. Finally, if the problem persists, a Servicing Dealer should adjust the carburetor.
What to do if Efco Brush Cutter engine starts but will not accelerate properly?
If your Efco Brush Cutter engine starts but won't accelerate properly or doesn't run well at high speed, the carburetor likely needs adjustment. Contact a Servicing Dealer to handle the carburetor adjustment.
How to fix Efco Brush Cutter when engine starts, runs and accelerates but will not idle?
If your Efco Brush Cutter engine starts, runs, and accelerates, but won't idle, try turning the idle speed screw “T” (Fig. 20) clockwise to increase the idle speed. Refer to the Operation-Carburetor Adjustment section for more details.
How to troubleshoot Efco Brush Cutter engine that will not start?
If your Efco Brush Cutter engine won't start or only runs for a few seconds, there could be two reasons: either there's no spark, or the engine is flooded. First, check for a spark at the spark plug tip. If there's no spark, try again with a new spark plug (BPMR7A). If it is flooded, follow the procedure on page 28. If the engine still won't start, try the procedure again with a new spark plug.
What to do if Efco Brush Cutter engine runs but cutting attachment is not rotating?
If your Efco Brush Cutter engine starts and runs, but the cutting attachment isn't rotating, the clutch, bevel drive, or transmission shaft might be damaged. If any of these parts are damaged, they will need to be replaced. Contact a Servicing Dealer for assistance.
