Mike, about the only way to solve this problem is to pull the cylinders
and break the glaze on the surface by honing them. You could reuse the
existing rings but I wouldn't recommend it, as they are probably glazed
as well. But should you decide to do so, check the ring end-gap
clearance byremoving the rings from the piston, then  pushing the ring
down into the cylinder with the piston until it is about where it would
be towards the top of the stroke. That will give you the minimum end-gap
clearence. Check with a feeler gage to see if the end gap is still good.
If not, replace the ring. If more than one is out, replace them all.

Good luck,
