Yes, my recollection is that the front and back carb ARE vaccuum operated. The motor normally would run off the middle carb. You could possibly get progressive linkage but since the carbs were not designed to work in this fashion, the motor would run very poorly because of the lack of accelerator pumps on the vaccum operated carbs. What you would experience would be bogging. You CAN change out the springs that control the opening of the vaccum carbs with WEAKER ones which would allow the carbs to open sooner.
