Get yourself one of the crank nuts/sockets as described by Rooster's 67. Pull the plugs and put some Marvel Mystery Oil in each cyl. Work it back and forth with an impact wrench. Ya might break something with the breakerbar. Did the same thing with a 4 cyl. industrial engine. Took a little while. (It won't happen in a second) Once it's free, disassemble and repair as necessary. Hope this helps?
