What I would do is remove the bar and chain. In the side of the bar are a couple holes that feed oil from the saw into the bar grooves. Make sure these are clean of any debris. Then look at the side of the saw where there is usually a wear plate and make sure the groove there is also free of debris. Lastly I would start the saw WITHOUT the bar and chain and look for oil coming from the groove area described above. If nothing coming out then you have a problem with saw motor and would have to go deeper into it.

My Poulan Pro chain saw (model # PP4620 AVHD) doesot move B&C oil from the oil reservoir to the chain. How can I repair this?

If the ports where the oil comes out aren't clogged, you will have to order a oil pump and then take apart the saw from right underneath the bar. The oil pump is run by a worm gear that strips easily.

My Poulan E300 Electric Chainsaw stop oiling the chain and bar

Hello JK; I am hesitant to answer this, these are all Poulan electric chainsaws that appear when the parts source is searched for Poulan Electric Chain Saws:
400E Poulan Pro Electric Saw
400EX Poulan Pro Electric Saw
ES400 Electric Saw
PP250E Electric Saw
PP300E Electric Saw

All are plumbed the same to my eye. I assume you cleaned and tested the oil pick-up within the tank. If everything you say is true if the pump is driven it should oil.
1. What causes the pump to pump? I cannot tell from the IPLs. If gas and not gear driven, an impulse line (pressure/vacuum) from the crankcase drives it. There can be no impulse line on an electric and I see no gear. Does it rotate to pump oil? What imparts the rotation?
2. What purpose does item 27 (pinion) serve? Is it supposed to drive the pump? Is it missing teeth?
3. What is the purpose of item 44 (check valve). If it is an oil tank vent, and not opening, you are creating a vacuum in the tank if the pump is operating. Loosen the oil cap and see if it oils. If yes replace the check valve.

I think Joe Schmoe is saying Poulan redesigned the oil system to eliminate all the hose couplings. It makes sense, one hose from oil pickup (filter on hose end in tank) to bar is much less likely to leak, also no restrictions for any particles in the hose to form a clot on. I see nothing on my research to support Poulan doing that. There are a couple of new models that I cannot find an IPL for so it is possible. I have headache JK. If this does not solve it is not because I did not give it my all. Please post back (below) with success or failure. If successful what was the cause. TIA

Poulan Pro 42/18 gas Chain saw: The chain oil hole that feeds the upper slot seems to be blocked. Does that rubber assembly just pull out or does the whole area have to be taken apart. Is it gravity feed...

GS, there is a pump driven by the clutch sprocket/drum. Operate the engine with the bar off. There should be oil coming out.

a) If so, the hole in the bar is plugged with saw dust. This is very common on all brands of saws.

b) If not, then remove the clutch/drum assembly and inspect the worm gear drive of the pump.
*note, the threads on all chain saw clutches are Left Hand reverse threads.

Poulan oiler don't work

Common problem with Poulan and Craftsman gas saws. Take off the chain and chain guide and clean out all the saw dust etc. Start saw without chain and look for port where there are signs of oil. If port is clear of sawdust, then it is likely the pump which is located behind the chain break assembly. you can get the diagram on Poulan website and the replacement pump will cost about $15 - $20 to replace yours.

I would like the fuel mixture for my poulan chain saw. %oil,%fuel

If you don't know the model, then go with a 35:1 or 40:1 ratio. 40:1 seems common on most smaller saws from Ryobi and Poulan is a relation to those. The 35:1 suggestion is just for a little buffer in case. Generally it is ok to run a richer oil mix. It just means you may have to change spark plugs more often, however, your combustion chambers will be better lubricated and probably last longer!

Sometimes there is a little sticker or marking on the fuel tank cap or somewhere near it that indicates advisable oil:fuel ratio... Have a close look, it may be indicated somewhere on the saw itself.

Bar sprocket smokes, gets hot spot

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.
