[QUOTE="Ford Fanatic, post: 132430, member: 24422"] Thanks for the ideas guys. As for squirting gas in the carb, that made it bog down. And I guess I should have mentioned that I had the exhaust off already checking for mouse nests etc. It is still essentially "straight piped" right now. I blew air through all the "header tubes" for lack of a better term. no blockages on the exhaust or intake. There was a leak between cylinders 2-3 but thats taken care of now. @ dfb-Thanks for jumping in, because that sparked an idea that I'm gonna run past you guys. First of all, I already have the governor disconnected. But the idea that you gave me is about the timing advance system... That topic in particular is something that I'm somewhat confused on...here we go. I understand timing, and I understand advancing/retarding the timing and what that means. However, if I take the dist. cap off, (engine not running of course) disconnect the vacuum advance hose from the carburetor port and I suck on it, I can see the electronic pickup (I think that's what it's called) being drawn "clockwise" The distributor rotor turns counterclockwise, so that would mean that more vacuum = more timing advance.
