That device would be your “right foot”.
The carb can be setup so that all four barrels open at the same time. Manually open the throttle and look down the bore. If all butterflies are opening simultaneously, yours has been setup for drag racing. There is a linkage adjustment that will open only the front two bores until the throttle is depressed more than halfway. Then the back barrels open.
