It was more of an annoyance than anything.... And well I wont have to worry about anything other than a final minor tweaks on the carb to better mate it with my engine. And blow thru set ups are run with Holley double pumper carbs. Vacuum secondary carbs do not work with blow through, because there is no vacuum once you start to get on the throttle
which is why I thought you were referring to the distributor lol
