What to do if my Dolmar PS-7910 H starts then dies?
If your Dolmar Chainsaw starts but dies immediately, it could be due to several factors. Check the idling adjustment, and clean or replace the fuel filter and carburetor if they are dirty. Also, the tank venting might be defective, the fuel line interrupted, the cable defective, or the STOP switch defective. Finally, a dirty decompression valve can cause this issue. Repair or replace the tank vent, fuel line, or STOP switch. Clean the decompression valve.
