  If your Dolmar Chainsaw engine doesn't start or starts with difficulty, several factors could be at play. It could be a malfunction in the fuel or compression system, or even a mechanical issue. Begin by checking the ignition spark and fuel tank, and ensuring the carburetor is functioning correctly. Also, inspect and repair any wiring issues, or replace a defective plug cap or spark plug. Ensure the choke is in the correct position, and clean or replace the carburetor and fuel filter if necessary. Examine and replace any defective packing rings or piston rings. Replace the spark plug if it does not seal properly. Finally, check if the spring in the starter is broken, or if there are broken parts inside the engine; repair or replace these as needed.

  If your Dolmar Chainsaw engine starts but dies immediately, the issue could stem from a few potential problems. Check the idling adjustment and adjust it if necessary. Also, the fuel filter or carburetor might be dirty, so clean or replace them. Inspect and fix the tank venting, fuel line, cable, or STOP switch. Another possible cause is a dirty decompression valve, which should be cleaned.
