Chainsaw Repair

I still have an old Rev-co I bought back in the 90's, it is on its second battery and is good as day 1.

For everyday work saws, I simply tune by ear. I think a lot of guys place too much need in tacks and forget how to correctly  tune by ear.

Regarding hotsaws, I think tuning them by tack and reving up to see how high it will go is only going to result in a suger bag full of bits and pieces instead of a race saw. (learned the hard way)

As for saws running 120, that requires a different set of skills to make them run right.

Just my views on the subject, and i'm no expert by any means.
