Try a good brand of penetrating oil through the spark plug hole first.With the engine secured to a rigid stand and a good pair of leather palmed gloves, try to work the flywheel back and forth to see if you can break the rust.
Even if you can get it free, there is already damage to the cylinder walls from the piston rings corroding on them. Also, the piston rings are likely corroded to the piston so you wont have a very good seal. I would recommend taking this engine apart and properly cleaning it up. And yes, the piston might have to be pounded out.
Your lucky, I had to do this to a V8 once. I went through a lot of lumber pounding 8 pistons out.

Pour diesel oil or Marvel Mystery oil or even brake fluid into the spark plg holes. Let it sit a couple days. Grab it by the prop or however you can turn it over by hand and try to move it back and forth. Keep repeating the whole thing untill it moves all the way., then put some more oil in there and turn it over lots and lots to loosen it up. Put in a little carb cleaner to clean out the oil (alot of oil comes out the plug hole when you turn it over). Put your thumb over the hole when you turn it now to see if it has compression. Put it back together with fresh plugs. You might need some starter fluid to get it going (make sure you have a spark). Give it a fresh oil change before you run it.

the oldest trick in the book is to use red diesel
a pore some into the engine and leave for a week or so and then empty the diesel out and
then place in a oven to warm the engine up
when it is hot remove from oven with welder
gloves on, and place the crank-end in a vice
tyeten up the vice and turn the engine slowly
until it comes free if not repeat the proses??

It wont be easy. I think the best way to do this would be to remove the connecting rod for that piston (which means basically you will have to disassemble the engine) and hammer the piston out by using a peice of wood and a hammer.

A mechanic once told me to use diesel fuel to get stuck pistons going. Let it soak for a while. Apparently it's an excellent lubricant and penetrated well. I've never tried it though but I believe him.

Try that stuff they call Marvel mystery Oil
I heard it works wonders
Pour it into the spark plug hole and let it sit acouple days
Keep doing this for a week if no results than you will have to disassemble the engine

pour in enough coca cola in the sparkplug hole to cover the piston, usually 6 or 7 oz's. leave it in for two or three hours and try turning the engine over without the starter.Turn the flywheel by hand either with the pull rope,if it has one, or with a screw driver.Don't leave the coca cola in there any longer then two days.

Yes on the diesel. Pour some in through the spark plug hole, replace the plug, and leave it a few days. Repeat!

Take out the spark plug and spray penetrating lubricant into the cylinder and let it soak in for a day.
