It’s not ignition related I don’t think. Car runs great all day, shut it off overnight and go back out and it bucks and shakes under load. Plus the whole garage smells like a gas station. Pull the plugs out, black as soot. I don’t want to just change parts around so I am gonna hold onto this 770 a couple days. I plan to take it off and inspect for obvious flaws. I am gonna replace base gaskets cause Holley said it may be a vacuum leak and then I am putting a regulator on it. Of course with fresh plugs. If that doesn’t work then we will know.
