Dual quad info
I'm having trouble expressing this clearly.
As always I hope pictures will help:
This is what I mean when I say throttle stud:
This is what I mean when I say throttle cable:
and this is what I mean when I say throttle shaft ( I am pointing at the end of the shaft). The throttle shaft goes through the butterflys in the bottom of the carb. Unfortunately once you put the chrysler throttle linkage adapter on the carb it is hard to see the end of the throttle shaft:
Typically the primary carb uses the factory location for the throttle stud that carries the accelerator cable and the kickdown linkage. The secondary carb starts to open when the primary carb is 2/3rds of the way to WOT and opens 3 times as fast so that they are both wide open at the same time. To accomplish this, the throttle stud on the secondary carb throttle bracket needs to be attached at a location that is 1/3rd the distance from the throttle shaft to the throttle stud as compared to the primary carb. That way the same distance of travel of the throttle cable produces 3 times as much rotation of the throttle shaft. If I were you, I would get 2 chrysler throttle brackets from Edelbrock so that everything lines upon the two carbs.
Clear as mud, right?
