That many chips indicate bad things. The plating is either delaminating on its own or something hard got banged around in there for a long time. Neither is good.
I would either put new rings on the old piston and run it or replace the whole cylinder and piston. Considering the cylinder and the age of the saw, the bearings probably aren't in great shape. I would plan on a full rebuild fairly soon.
I would probably run it until it dies and then rebuild.
