With the AFB dual quads I had many moons ago, the front carb did not have idle screws, and the rear carb acted as the primary where you adjusted the idle. The front carb did not function until the progressive linkage activated it.

Rumrumm, do you think that helped the dual quad - cough, cough - MPG?

That was back in 1969-71 when gas was 28 cents per gallon. Gas mileage? I didn't need no stinkin' gas mileage! LOL!
