I know that when new rings are installed in 4-cycle engines that it is
generally recommended that the cylinder walls be honed to remove the
glaze, so the the new rings will seat properly. Is the same true of
2-cycle engines?

I expect it is, but I just thought I'd check.

Majority of the time. *There have been a few 2 strokes that used chrome
cylinders. *Those can not be bored or honed. *It's unlikely that you have
one but pretty obvious when you look at them.

I was told that the cylinders become somewhat oblong rather than round in
diameter on engines with a lot of hours and usually require boring first
when rebuilding.

One thing to watch out for, is taper. If the bottom portion of the
cylinder bore is out of spec, you can get piston slap. If the bore
gets too large, it can slap so hard that the piston skirts break.
