Nice job. Wood looked like marble with the knotts.
I guess that it is a regular carbed saw?
Any idea on compression?

M-Tronic saw. I'll ask him about the compression. It was a brand new saw. Got straight gas on the 3rd or 4th tank. He paid $100 for it, cleaned the cylinder up, I gave him a piston and there are the results.

Being the saw is a strato is the piston an exact copy of the oem so that the timing remains the same?

I'm getting one. Gonna Mic the entire slug.

@Jchin is allowing his 261 to be the Guinea (why you gotta say guinea?) Pig for this slug. Planning on a muff mod, then before and after slug swap including base cut for .015 final squish.

I will video pulling a bar size it has no business running.
