Husqvarna 460 Rancher won't get oil to the chain..

[WoodyReedy]

My Husqvarna 460 Rancher, 24" chain, is not letting oil get to the chain. I repaced the metal oiler, the plastic oiler drive gear and the rubber distribution tube, but it didn't make any difference. I have the oiler set to it's highest setting, (turned counter clockwise to its third setting), and yes, I have a full tank of oil. When I blow into the mesh filter that is beneath the rubber tube, oil does come out of the oil hole. The distribution holes that are in my bar are not clogged. A little oil gets to the chain but not much. It uses about a 5th of the tank whereas before the trouble started it used about 90 percent. Any suggestions?

The oil tank breather could be blocked

When I blow into the oil tank breather, (the gold mesh that is beneath the oil distribution hose), oil comes out of the oil hole from the tank, so that doesn't seem to be the problem.....
