Quote: just thinking here, why would a professional carb shop put black springs in the diaphragms? using black or brown springs was something thats done when the kill bleeds are blocked. blocking the kill bleeds brings the end carbs in rapidly and heavier springs are installed to compensate for it. if you have a cold intake the problem gets worse. you don't state the engine build, what is it? i think some of the aftermarket parts are more gadjet than necessary. i have two six pak cars that drive beautifully and i've never seen a reason for the gadjets. i've been playing with the six-paks since 1970 and for all practical purposes they just don't need to be re-engineered.
Couldn't have said it better.Here are the last three sets I did a few months back,if you would have seen how they were screwed up and some of the so called modification it would boggle your mind.I to have been doing them since the early 70's and could probably write a book.
