  If your Dolmar Cutter engine doesn't start or starts with difficulty, it could be due to a malfunction in the fuel supply system, compression system, or a mechanical issue. Other potential causes include the STOP switch being on, a fault or short-circuit in the wiring, a defective plug cap or spark plug, an incorrect choke position, a defective carburetor, a dirty suction head, a bent or interrupted fuel line. Additionally, a defective cylinder base packing ring, radial shaft packings, cylinder or piston rings, or a spark plug that doesn't seal could be the cause. Finally, a broken spring in the starter or broken parts inside the engine could be responsible.
