Why won't my Dolmar Brush Cutter engine start?

  If your Dolmar Brush Cutter engine won't start or struggles to start, several issues could be the cause. Check the STOP switch position, look for wiring faults or short circuits, and inspect the spark plug and connector for defects. A faulty ignition module could also be the culprit. Other potential issues include an incorrect choke position, a defective carburetor, a dirty suction head, or a bent or interrupted fuel supply line. Additionally, inspect the cylinder bottom gasket, crankshaft seals, cylinder, and piston rings for wear. Ensure the spark plug is properly sealed. Finally, a broken starter spring or broken parts inside the engine may be the reason.
