Alrighty... I just bought the vacuum gauge! What do I need to do? I've got a Chevy 305, Edel 1406 Carb & Edel 2101 Intake. My problem... Doesn't want to tune properly & everyone suggested a Vac Gauge. The motor seems to run fine when going down the Highway but...When Ideling, it wants to spit & sputter. When I kill the engine... It wants to continue to run. I really need some Great advice when it comes to getting this motor dialed in w/ the gauge. I'm to the point that I want to try anything.
