OK, this will be the third time I’ve tried to reply to this thread….

In any event, that propeller did not come with this engine, so chances are good that the engine was run.  Frank poses an interesting theory, sure hope he is wrong though.  I keyed in on your comment about both the powerhead and the throttle being seized up, perhaps this is more than just coincidence.  Perhaps some came loose under the flywheel (hardware/busted coils) and had jammed the flywheel/mag plate.  Have you removed the little inspection cover on top of the flywheel and had a peek under there?

I suppose the recoil could be jammed, but that isn’t very likely.  Have you removed the recoil and tried moving the flywheel?  It is also possible that the gearcase is jammed up causing this issue, have you drained the gear lube?  Perhaps the rings are just lightly stuck, perhaps it will free up if you put a socket on the flywheel and try rocking the flywheel back and forth.  Please be careful, don’t crank down on the flywheel nut or use an impact gun on the flywheel nut.  Have you removed the plugs?  If so, do they look rusted?  Those intake bypass covers come off easily on the right side of the powerhead, which will allow a closer look at the piston rings/skirts.  Check to see if the rings are stuck in place.  Not a great idea to just run the engine with stuck rings, especially on a beautiful engine like this.

Let us know what you find…
