Hi Bill,
Are they grooves or ridges. Often where the rings stop on the upper end
will leave a ridge. In my teen days they sold a deridge device that
went around the top of the cylinder to remove this. It wasn't a
cylinder hone but something else. Anyone on the list know about these?
I would check for taper, if your cylinder is showing signs of taper then
bore it out. BTW I would have the machine shop supply the pistons
because you won't know whether it needs to be 10 or 20 over bored. If
you show no signs of taper I would deream it to remove the ridge and
call it good.
