I have a brand new 372xp, I am using a 24" husky bar and chain. For some reason it isn't oiling? If I take the bar and chain off and let it idle all kinds of bar oil comes out of the pump, the oiler hole in the bar isn't clogged, and the drive links on the chain are in good shape. As of now I have the oiler turned all the way up. It cuts fine but when its buried it obviously isn't getting enough oil. Anyone have any ideas before I take it to the dealer?
