Chainsaw Repair

OK, might as well get some thoughts on this. In my experience stock saws can have any where between 0.030 and 0.050 squish. When building I shoot for 0.020 or as close as I can get without going below 0.020.

I got a saw in Thursday last that was built a few years ago by an out of state builder, it had 0.018 squish, ran pretty well. Not my saw, I was asked to put new seals in it because the owner thought it had an air leak, it did.

Anyway I was wondering if anyone had opinions on what would be a good rule of thumb for minimal squish?

Squish is the clearance between the piston crown and the top of the cylinder.

Awesome, thank you.

I've heard of some porters using .018 that are pushing it for every last dime and worked fine for them.  Most I seen on mine  were .020-.022   

What saw?

I had an 084 that was .110...it ran ok. I got it down to .020 and it runs better but also a lot harder to start.
