Most of these old motors that people kept around haven’t
seen anywhere near enough use to need rebuilding and
honing the cylinder to replace rings it doesn’t need in the
first place is more likely to result in a loss of compression
rather than an increase.
I don’t mean to beat you up but if you don’t have
any ware or taper in the cylinder there wasn’t anything
that needed fixing. Honing the cylinder out .002 will
increase the potential movement of the piston by
.004 side to side, front to back. Then there is trying
to get the new rings to seat as well as the ones that
were taken out.
I would suggest knocking the glaze off with some 400
sand paper, gap the rings and put it back together.
