Question about Poulan Pro Chain Saw 46cc 20"
Poulan Pro PP4620AVHD 20" saw, runs great, shows oil on bar near powerhead but bottom of bar near sprocket gets hot spot, somkes & eventually siezes up. Bar does not look worn or bent there. Using Poulan bar oil.
Used spray brake cleaner & cleaned out oil port & bar grooves, but still does it.
Sounds like you're not getting enough oil to the chain. Basically you've got an oil pump, pickup and filter involved in getting oil from the resovior to the chain/bar. If you cleaned the obvious area and the chain is not coated with oil, you may have a clog further up (inside) the oil delivery mechanisms. Also, drain the oil from the tank, and see if you can "blow" air through there. With the saw running & pointed down, you should be able to see oil on the ground being slung off the chain, if not, you are not getting enough oil to the chain.
