Thank you for all your comments - they have been very helpful.
So far -
the plugs are a nice tan color.
The cyl's looking through the exhaust port, I can
see the cross hatch marks.
I can also see two scratch marks one horz and
one ver appx length of 1/4 inch.
No visible scratch marks on the pistons.
With the plugs out the engine still sticks.
Although after my last post I was able to move
the prop with some effort. But then, each time it
sat for a while it stuck again, even with plugs out
it stuck.
The engine was stored here in North Idaho for about
10 years and a good chance that moisture got into the
crankcase and some rust developed on the bearings.
So the only way to find out is to tear it down.
I'll let you all know what I find.

Cecil,
I don't buy for a second that bearings would seize the engine in the manner you describe. I would tear down the top end first, you will probably find your problem there.

It could also be something came loose in the mag end or in the gear box. It seems by your description that something must not have been assembled correctly, not tightened or left out at the factory.
I had a chain saw that would lock up when trying to start it occasionally. It would run fine when it started though. I finally took it apart and found there was no circlip to hold the wrist pin in the piston. The wrist pin would catch on the transfer port in the cylinder.
Another time I had one of the original Sea Doos with a single cylinder Rotax engine. One of the screws that holds the magnets in the magneto backed out and caught the outer mag housing and locked it up.
