  If your Makita Lawn Mower engine is difficult to start or loses power, it could be due to dirt, water, or stale fuel in the tank. In this case, drain the fuel and clean the tank, then fill it with clean, fresh fuel. Another possible cause is a plugged vent hole in the fuel tank cap; try cleaning or replacing the fuel tank cap. A dirty air cleaner element could also be the culprit, so clean the air cleaner element.

  Your Makita Lawn Mower engine might be overheating because the cooling air flow is restricted. Remove any debris from the slots in the shroud, blower housing, and air passages to resolve this. Another cause could be an incorrect spark plug. Install an RC12YC or QC12YC spark plug and cooling fins on the engine.

  If your Makita Lawn Mower engine is operating erratically, it could be due to a defective spark plug. In this case, install a new, correctly gapped plug. Another potential cause is an incorrect spark plug gap; set the gap between electrodes at 0.7 to 0.8 mm. Also, a dirty air cleaner element can cause this issue, so clean the air cleaner element.

  If your Makita Lawn Mower engine idles poorly, it might be due to a dirty air cleaner element, so clean it. Alternatively, air slots in the engine shroud could be blocked; remove any debris from the slots. Cooling fins and air passages under the engine blower housing could also be blocked, so remove any debris from these areas.
