When I bought the '77 Ramcharger, I was able to drive it home but it really had no power, snapped through the carb if you gave it any amount of acceleration other than just creeping out of the hole. I found several things not right including spark jumping in weird spot in the dizzy, ignition timing off, vacuum leaks and the such. Got it sounding pretty good now, although I decided to put a new master cylinder on it so the old one is off. It has hardly been driven since 1999, so gotta chase some cobs.... LOL
