My thought would be that seizing it damaged the piston/cylinder and
possibly the seals as well. Pull the top end and take a look at the
cylinder wall to see if you can get by with a piston/rings or if you need
a whole new top end. It's not unusual for seized 2 strokes to run again
after cooling down but they seldom are ever the same. When's the last
time you had replaced the impeller?
I didn't, because I kept seeing water coming out the pee hole. That's part
of why it's my own fault. I knew better.

The cylinder head is easy enough to pull without taking the thing out of
that clamshell case, so I guess I need to do that before thinking much
more. The parts list indicates they had .020 and .040 oversized piston and
ring sets available, though they would probably be next to impossible to
find any more now. But, you never know. Somebody might have some gathering
dust on a shelf somewhere. In any case, that would seem to indicate that
the standard piston/rings are good to .010 over size, at least. Perhaps if
the scoring isn't very bad a bit of machining would help. I own a farm,
and have been known to rebuild an engine or two in my time. Trouble is,
most of my experience is with four-strokes in tractors and combines.

This old motor and I have been through a lot of good times together, and I
really hate the idea of giving up on her without a fight. Between now and
the end of the growing season, though, I have to spend my time making a
living.

Yea, you've got no one but yourself to blame if you tried to get 20 years
out a rubber impeller.

That they only have 20 and 40 over does not indicate that you can use a
standard piston in a 10 over hole. A 2 stroke will have hgiher clearance
built into the piston size already. If it needs boring to remove scoring
then you need to find a 20 or 40 over piston. That would be the next thing
to research after you take a look at the cylinder. You might be surprised
about the piston. Some of those smaller engines were built in various
configuations using the same pistons for a long time. You might also find a
use top end somewhere but after this many years the chances of any not being
pretty worn out are slim.
