How to "Un-Stick" a stuck motor?

This has happened a few times to me and I think I am missing something simple? I have a scooter motor out of the bike and it turns over with the kick starter. Then, it seems to get jammed (frozen) and will no longer crank. Its not like the piston is stuck (I don't think)...seems like it needs to have pressure released or something? Is any of this making any sense? I don't think it "grenaded" in there from manually cranking the thing or something. Any ideas?
Thanks

Try cranking it with the sparkplug removed.

If you have the motor out, turn it upside down and crank.
It could be oil/ fuel lock up.
I've seen this on several scoots that were sitting for long periods.
Exhaust may be full also.

Put some 2 stroke oil in the cylinder to lube it up and allow free movement.
