Nick: I have the 57 dual quads you mention on my 56. I plan to change them out when I get the original 56 factory dual quads ready to go. Anyway, I have the slotted linkage that is correct for these carburetors and have it adjusted so that I operate only on the rear carb until I get to highway speeds or decide to romp it a little. To do this, I have left a space of about one half inch on the front carb to keep both front throttle valves closed until I want them. This is not very scientific, but it works and saves me gas. If you want it more precise, decide at what rpm you want the front carb to function, set the throttle to that rpm and adjust the linkage accordingly.
