Air leak could be .

To honest with you this was not the machine out there, it is basicaly a 236, an American built hobby saw, air leak maybe, the main bearing sit in rubber carriers which also incorperate the crank seal, it is a full stip to replace these, they were very prone to shed there maun bearing cage, which will nip the piston ring in, again replace bearings, and possibly piston, please check easy /cheap things first, fuel filter in the tank, split or cracked fuel hose, gaskets between the carb and manifold, gasket between manifold and cylinder, there is no gasket between the the cylinder and crankcase, here you have instant gasket, try re sealing, carbs were not the best, you need a special tool to adjust the jets as they the screws have splines, if they came from e bay who knows what can have be done to them, try just richening the H screw.

Thank yo very much for your advice after checking all of the cheap parts to check i have completely striped down the chainsaw and found a lot of wear on the crankshaft seals so will order a new set and then see how it runs and ill keep you posted

 

Thanks again

Sounds like air leaks, but I know very little about those saw, except they are crap, even compared to other cheap Poulan made Husky saws....

Saw Troll if you know very little about this model please do not say it is crap, i grant you it is not the best hobby saw out there, but it is a hobby/entry level machine, if used as a domestic machine cutting a few logs for the log burner it is fine, its horeses for courses.

All I will say on this is, my profile picture is a Husqvarna 236 on that stump, they aren't screamers, so you probably have an air leak. Replace the fuel lines, carb kit, etc. you'll need a dealer or special tool to adjust the carburettor. You'll also need liquid sealant for the cylinder when you rebuild it, and watch the plastic transfers don't drop out.
