I have one cylinder that is 30 psi rest are 120.  I pured oil in the cylinder and rechecked and it jumped up >100. So I guess I am looking at rings/piston-who knows.  Speedo says 75,000, but i could be 275,000 for all I know.

Is it worth it to try to rebuild these sammy motors ( bucks) vs replace ().  Where can I even find a used engine?

This is depressing, I was looking forward to fixing my new toy-
thanks for the help.

Get a set of rings, some rod and main bearings and have the valves
either ground or replaced depending on their condition, then put in
a new water and oil pump and a new timing belt, you need a gasket
set and hone the cylinders, this will reuse the old pistons and go another
trip around the planet before you need another engine.

This is like $300 in parts and a whole lot of satisfaction that you brought the
engine back to life

where is the best place to order the parts needed to rebuild?
Thanks a ton

Low Range Off Road has great service.  Sammy Pro is another good source when dealing with engine related items.

I bet you can find a good 1.6 8 valve to drop in it for about the same $ and less work and get more power to boot . But then of course, you won't have the satisfaction of building your own engine, several times if you've never done it before!
