Try to see if the piston is moving, you may be able to see it through the exhaust. If it's at top or bottom center it may move a little without moving the piston. Try to get some penetrating oil in the cylinder, you may have to remove the ignitor. If the piston is moving, it should go with the oil, if not you may have to take it apart.

I would try some Aero-Kroil shot in from all angles and let it set for a week. Each night squirt it again.
If that doesn't free it up, try to figure where the piston is by taking off one of the side plate covers.
Sometimes you can remove the rod from the crankshaft and also remove the base. This may allow you to drive the piston up toward the top with a few hammer raps on a piece of end grain oak placed on the piston skirts, wrist pin bosses, etc. If she budges, keep doing it. If not, soak again with the Aero-Kroil and try the next day, etc. ( Lather, rinse, repeat. )
If push comes to shove, you may have to take the priming fitting off the top of the cylinder and fill the cylinder up with grease. Keep pumping with a grease gun until she is full and then eventually this will develop presure enough to move the piston down to free it up...if you are lucky.
If the piston is in such a position where the grease just can't seal above the piston, you may have to give things a bit more thought.
Try the Aero-Kroil. It is much better than WD40 and other such products. Look it up on Google, they sell online.
Aero-Kroil is mostly turpentine and so you can try that if you don't want to buy the Aero-Kroil. The price is about the same as WD40, however.

If it is at the bottom of the stroke, pull the cylinder and hone it, Refit and try it again.

Sometimes the water jackets inside the cylinders will rust so badly that the pockets will fill with rust. this can cause pressure on the cylinder and can actually deform the inside cylinder wall(causing the piston to get stuck) , and in some extreme cases put a bulge or split the outside of the casting.this is definatley something to look for when buying an engine that has been sitting around for a while.
