I've had this saw for about 6 or 7 years now and until lately it's been a decent tool, starts right up and runs well. I don't know exactly when it started but the chain lube system is definitely not working any more and I can't figure out how to take it apart. I read through the manual and it doesn't help me at all. I'll take some pictures tomorrow of the parts I'm looking at but for now I was wondering if anybody has a poulan and has ever encountered this problem.
