The oil has stopped coming through to the sawchain on my rather old chainsaw.
I learned (belatedly) from a chainsaw manual that if not used for long periods, you should empty the oil reservoir. If you fail to do that, you should empty it, put in some ordinary engine oil, run the saw for a while, then empty again -- the channels should be free.
No luck with this technique so far, so ... are there any old tricks to freeing up the channels that I might try? I know there are several time-served chainsaw users in this group!
