    Edelbrock 1406 Jetting

    I've been looking at a few forum posts looking for what people have found with tuning and jetting their carbs, and maybe I'm confusing information, but some people seem to be maybe using different jets for the secondary side? Unfortunately working long hours and the car being parked for the...

    I have a 79 gmc c6000 with a 350 in it. The truck is not starting... it turns over but will not engage in starting.

    Engine cuts off when I press on the gas pedal

    I have a 78 k10 with a 350. For some reason, when I press on the gas, the engine cuts out. Is this caused by the fuel/air ratio, the choke, or something else?
