Echo CS-600P, piston is scored on exhaust side. I suspect the cylinder wall is equally scored. I know on car engines cylinders are honed to remove scratches, and depending on how deep either oversize rings or else a larger piston is used.
Has anyone ever done this for a chainsaw cylinder? I can replace the piston, but the cost of a new cylinder makes it not worth fixing this saw.

You dont really need to use a ball hone at end like I do. But I like using them for a fresh crosshatch after cleaning the transfer off the plating by steps 1 and 2.

590 I did just like your asking. I just used a new piston kit. Cleaned cylinder up. Get a new base gasket. Echo base gaskets tear easy.

Last 2-3 pages of doing 590 http://chainsawrepair.createaforum.com/echo/cs-590-wolf-review-bone-stock/
