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.
