This is just hearsay ..... I have an Edmunds intake that uses these same type of carbs. My thought was to be able to set them up so one of the two barrels on each carb would be for cruising, but the other two barrels could be used to kick in with a "throttle stomp". I have been told this will not work because the size of the barrels will not allow a large enough volume of gas through them on to run with one barrel on each carb. If you think about it, however, unless it would work that way, what would be the point in running this type of carb?
