If your warm Dolmar Chainsaw engine doesn’t start, it could be due to a wrong carburetor adjustment or flooding caused by excessive choke usage. Adjust the carburetor and avoid excessive use of the choke.
Why won't my Dolmar Chainsaw start?
Several issues could prevent your Dolmar Chainsaw from starting. It could be a malfunction in the fuel supply or compression system, or a mechanical issue. Check the ignition spark, ensure the fuel tank is full, verify the starter engages, and inspect the wiring for faults. Other potential causes include an incorrectly set choke, a defective carburetor, a dirty fuel filter, or a bent or interrupted fuel line. Adjust the choke, clean or replace the carburetor and fuel filter, and check the fuel line. Also, inspect and replace any defective cylinder base packing rings, radial shaft packings, or piston rings. Replace the spark plug if it doesn't seal properly. Finally, examine the starter spring and any internal engine parts for breakage, repairing or replacing as needed.
What to do if my Dolmar Chainsaw engine starts, but dies immediately?
If your Dolmar Chainsaw engine starts but dies immediately, it could be due to several factors. Check the idling adjustment, and clean the fuel filter and carburetor. The tank venting might be defective, the fuel line interrupted, or the cable or STOP switch defective. Inspect the tank venting, fuel line, cable, and STOP switch. Also, the decompression valve could be dirty, so clean it.
Why is there no chain lubrication in my Dolmar PS-7300 H?
If your Dolmar Chainsaw isn't lubricating the chain, it could be due to several reasons. The oil tank might be empty, so refill it. The oil guide groove could be dirty, so clean it. The oil-pump adjusting screw might be incorrectly adjusted, so adjust the oil pump. Lastly, the oil pump drive could be defective, so check it for any issues.
What to do if my Dolmar PS-7300 H starts then dies?
If your Dolmar Chainsaw starts but immediately dies, the idling might be incorrectly adjusted, or the fuel filter or carburetor might be dirty. Adjust the idling settings and clean or replace the fuel filter and carburetor. Other potential causes include a defective tank venting system, an interrupted fuel line, a defective cable, or a faulty STOP switch. Repair or replace any defective components. Also, the decompression valve might be dirty, so try cleaning it.
