did you check the oiler for debris?
then run a very thin oil through it? (rev and shake the tar out of it)
it works a whole lot better with the bar out of the way.
then check the oil pump, and I dont know exactly how but I know you can adjust the flow.
try that, if you adjust it and get the oil flow going, more than likely it will oil too much, then slowly back it down to match the tank
I should be a rep for STIHL!
