I've got a Husqvarna 61 that doesn't seem to be oiling the bar sufficiently. The last time I used it, it appeared to quit oiling all together and got the bar pretty hot. I stopped using it, and removed the bar and chain. I found the hole the oil seeps through, and it wasn't clogged. I ran a small wire through it, and cranked the saw. To be honest, I don't know how much oil is enough, but it wasn't squirting out. It was basically trickling out, if that's the right term. Anyway, how can I check to see if its oiling correctly, and how do I adjust it? Also, how do I know if its is pumping out enough oil for the chain? Thanks!
