I have mounted one of the Halverson bars on a Mac 10 10 and run 4 tanks of gas thru the saw so far. A few problems so far, the bar gauge is .080 so the closest thing I can find is a .063 gauge. It's OK but could be better if it fit right. The other problem is the oil hole getting plugged with wood chips. And last unless the gap at the tip is very small the nose will compress a little and alow the chain to jump off the bar. Except for that it works fine. LOL Is there such a thing as 3/8 pitch .08 gauge saw chain?
