Sentinel prime my 51 gmc has a 292 transplanted in it. I am trying to check this out to install new points coil etc. The engine won't turn by hand. I pulled out the plugs and poured over two day half a big bottle of marvel oil in it. Tonight I got my 3ft breaker bar out and I'm afraid I'm going to hear off the crank bolt. It's only a 5/8th head. It has a five speed prob a Clark can I get to the flywheel from the bottom? I sure don't want to break that bolt trying to get it unstuck. Gee I ran when I shut it off. Famous last words.
