This will sound crazy BUT...I did it!! An engine I "found" was stuck. I poured the Marvel Mystery oil to it pretty heavy, pulled the heads and actually took a round piece of firewood that would fit in the cyl and put it on top of the pistons. I gave each one a couple good whacks then using a BIG slotted screw driver I finally got the flywheel to move..just a little. Then let it soak overnight and repeated the process. Once it got to moving I kept working the flywheel back and forth until it would make it all way around. Engine fired up, smoked like a tar kettle for a few minutes and then ran fine.
Maybe just luck but it worked!!! I have also "heard" that letting disel fuel soak for a while would help????

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
