You normally have 3 screws - idle speed - slow running and fast running.
First take care as if it runs faster than idle speed that chain will be whipping around also.

Second you have to determine what is the problem. Is it faulty at low speeds or high speeds ? or won't it idle.
If it has turn stops fitted to the screws you only have a small adjustments either way.

If it won't idle, try turning in the idle screw a half turn - until the chain just starts to move slowly.
If its dying at slow speeds, get is going and slow turn the slow screw out until it starts to run a bit rough then turn it back in to the point where its running smoothly.

Bad fast speed can be caused by simple things such as a blocked muffler ( insects too - I had one blocked off by a mudnest wasp) - otherwise get it running at full and adjust the fast screw as per the slow one - out till its rough then back in slowly until its smooth.

Suggest before all this tho that you get it running with the cover off the carby and then give it a good squirt of carby cleaner first - it may just clear out any 'poop' thats there.

(Have faith even tho I have a Poulan with a carb that refuses to run on anything but carby cleaner. I have pulled it apart a few times and renewed all the perishable bits buts its a real pig)

Chain on my Poulan 20 inch pro will not tighten


If you've got the adjustment all the way out, you may need to remove a link or two from your chain or replace the chain. You can find replacement chains at Partsbuggy.com.

Chain doesn't move


Sounds like the clutch is slipping due to oil collected on the inside of the clutch drum. Wash out the entire clutch assembly with spray carburetor cleaner and let dry. Make sure the chain can be turned freely by hand, but the chain doesn't droop from the lower bar edge. Hope this helps!

My poulan 360a chainsaw cuts out when used for 5 mins. when opening throttle to saw woods it does not respond and cuts out.it starts again ok but will not respond to throttle. it is ok when motor is cold.


Check the fuel filter for plugging, the fuel lines for hardness/cracking/splitting. Clean or replace the air filter. Clean the muffler if plugged. Make sure that the carburetor fasteners are tight. Check the spark plug condition--gap should be 0.020" and the insulator should be light to medium tan color. If still having problems, the carburetor may need to be cleaned and serviced. Hope this helps!

Chain saw won't start


Check the fuel filter for plugging (which is common when fuel is left in the machine over winter storage). You should run the carburetor dry after emptying the fuel tank for storage.Hope this helps!
