Hey fella's, my Poulan made 3.7 has developed a bar oil leak recently. Full tank or half tank, if left overnight there will be a puddle under saw. Takes several days to get near empty . Two years ago I replaced the gaskets and diaphragm and it has worked fine until recent leak. The manual and auto are still working. I have not been able to find leak. I replaced the cotter pin tank vent with a plastic tube vent that reaches across tank to opposite side , ( like a wild thing vent). I probably should have left the cotter pin in tho.
Has anyone run into this ? I appreciate any input. Chris
