If they are at the very top near the combustion chamber you may be ok. If it is down low around the ports you may have a problem. I think I would hunt down another cylinder. No point in wasting good rings and a piston.

So I got some acid and away I went.  The scoring was either worse than I thought or the acid burned through the Nikasil coating.  I now have a couple of small but seeable chips or breakes in the cylinder coating.  So, should I put it back together with a new piston/rings and run it like I stole it or get a new jug and do it properly?

To further complicate this question.  This saw started and ran pretty well before I removed the aluminum galling from the cylinder. I do have a new piston (Golf, maybe Chinese)) so I think I'll put it back together and see how it goes.  It that doesn't work out all I've lost is my time and a cheap piston but I will have gained a bunch of experience.
Thanks for your input, much appreciated.
