  If your Makita Chainsaw engine doesn't start easily, begin by inspecting the ignition spark and fuel supply. Also, verify that the combination switch is not on STOP. Check the wiring for faults or short circuits and inspect the plug cap or spark plug for defects. Ensure the combination switch is in the Choke position and inspect the carburetor. Other checks include cleaning the suction head, checking the fuel line for bends or interruptions, and inspecting the cylinder base packing ring and radial shaft packings. Finally, check the cylinder or piston rings, ensure the spark plug is properly sealed, inspect the spring in the starter, and look for any broken parts inside the engine.

  If your Makita Chainsaw engine doesn't start or starts with difficulty, several factors could be at play. It might be due to a malfunction in the fuel supply, compression system, or a mechanical issue. Inspect these components. Also, check the wiring, plug cap, and spark plug for any defects or short circuits. Ensure the combination switch isn't in the Choke position, and inspect the carburetor, suction head, and fuel line. Other potential causes include a defective cylinder base packing ring, radial shaft packings, cylinder, or piston rings, or a spark plug that doesn't seal. Lastly, a broken spring in the starter or broken parts inside the engine could be the culprit. Replace any defective parts.
