Thank you...Stuck...to UNSTUCK!!!

Congratulations. Hope to see it running soon.

I had success freeing a frozen engine with a homegrown concoction of Trichlorethane, Marvel Mystery Oil, Liquid Wrench, and a little motor oil. The reasoning to use Trichlor was to make a fluid light enough to penetrate around the piston rings and into the grooves. Because Trichlor evaporates quickly, the other chemicals go back to their original viscosity for lubrication. I just squirted a little into the cylinders daily for about one week. It broke free with a breaker bar and pipe.
