Chop saw cylinder question

[kz1000]

The only damage that I can find on this cylinder and piston are at the intake due to bad filter, would you clean it up and run it? It is smooth over the intake and a little ruff below, the piston wall on that side is a little ruff but would sand off easy. The rings were toast and I think it was allowing the piston to twist a little at bdc. It's a Wacker saw and I probably could sell the parts for more than I could get with a new cylinder kit. If I drop a ring in it and it shows good compression, I may just put it back together.

I don't think that's serviceable. The problem with chop saws is when they're run with a bad filter/no filter, the cylinder is effectively being sand blasted.

That area around the intake looks to have all of the plating gone. It would run for a time but poorly and that area wouldn't seal well and eventually would
wear enough to allow the piston to rock back and forth in the bore.

Thanks, I kind of wondered about it is why I asked. The rest of the cylinder looks great and a ring looks tight in it everywhere, but I can picture blow back into the carb from the wear at this point.

Clean it up and run it.

It's a gone'r.
Never liked the fact that Dolmar thought one ring was ok on a cutoff saw.....

Strangest thing to me is that the ring ends are in the intake zone and not left or right. Thant's just asking for trouble in my mind.

Spit back would probably be so bad when it warmed up, you won't get it to idle under 4k Rpm.
