So I'm doing a cam install with my brother and dad and we are stuck on this crank bolt. We have most of the top end of the engine off and the valve springs exposed. We've been hammering at it with a half inch impact wrench for a while with no luck. I've read about using the starter with a bar up against the frame, but when we hooked the battery back up and bumped the key, the starter didn't fire and gas started leaking (whoops) so, anyone have any ideas? how do you kill the fuel line and get the starter to actually fire? we've thought about applying direct voltage to the starter, which way does the starter turn the engine?
