Piston was taller and had a pop up so band cut w/ no base cut.
Pop up hit the plug, compression was excessive.
Relieved the pop up and raised ex. And transfers.
Was torquey and would keep on pulling but not great rpm.
Kept going up with exhaust to 98 or 100, can’t remember. No major performance change.
Wash pattern looked like pop up was dividing the transfer flow and sending some right out of the exhaust.
I ground the pop up off, flat top.
Compression by then was 165 ish.
Still have the saw, could use some more break in time.
Runs good but nothing to write home about.
If I were to do it again, I would probably leave a small flat pop up to get compression up around 200.
