  Several factors can prevent your Makita Lawn Mower from starting. The throttle chock may not be in the correct position, so adjust it. The fuel tank could be empty; if so, refill it. A dirty air cleaner element can also be the culprit. Additionally, check the spark plug: ensure it's tightened to 25 – 30 N•m, the wire is properly connected, the gap between electrodes is set to 0.7 to 0.8 mm, and that the plug isn't defective. If the carburetor is flooded, remove the air cleaner element and pull the starter rope until it clears. In case of a faulty ignition module, contact the service agent.

  If your Makita Lawn Mower engine is hard to start or loses power, consider these possibilities: the fuel tank may contain dirt, water, or stale fuel—drain the tank and refill with clean, fresh fuel. The vent hole in the fuel tank cap might be plugged, so clean or replace the cap. Also, check the air cleaner element; if it's dirty, clean it.

  If your Makita Lawn Mower is overheating, it could be due to restricted cooling air flow. Remove any debris from the slots in the shroud, blower housing, and air passages.

  An erratically running Makita Lawn Mower engine can stem from a defective spark plug. Replace it with a new, correctly gapped plug. Another potential cause is an incorrect spark plug gap; ensure the gap between electrodes is set to 0.7 to 0.8 mm. A dirty air cleaner element might also be the problem, so clean it.
