My 039 seemed to not be getting oil. Chain getting hot quick, not cutting well, smoking, etc.

I cleaned the daylights out if it. Ran briefly with no bar to ensure oil is coming out of the orifice. Cleaned bar, cleaned oil hole in bar, cleaned chain, and everything around the sprocket. No results. 

Saw looked like this after running. It appears that the saw might be leaking? Again, this was after a minute of running and was spotless before. Using Stihl bar oil. Chain looked wet but not slinging oil. Oil adjustment screw maxed

 

 

Known for problems with worm gear located under clutch plate, oil pump, or a leaking hose.  All simple fixes.  Best to google a few Youtube vids to help diag which one is the problem.  Still stuck send me a PM.

From a quick search on EBay it seems that there is a line going to and from the oil pump which would constitute the entire oiling system. I have some YouTube research to do but it seems cheap enough to just replace it all. Thanks!

I know on husquvarna there is an oil tube that can get blocked and you gotta take the thing apart.  Maybe same problem. Happened to mine last year.
