Laright carb guys i am having a problem i have two 1050s on my 477 in my canyon the motor runs great but when i shut it down its bleeding fuel out of the carbs and filling up number 6 cylinder for some reason they are on a pro dominator holley tunnel ram with a aeromotive a2000 fuel pump. My first guess im thinking maybe a needle seat is leaking by but in not real sure the floats are all good the only other thing i can think is going on is i have a solid driveline in my canyon so i have the motor sitting at the angle of the driveline so the carbs are at a little angle while sitting on the trailer. Do they make a wedge spacer to fix this problem
Angle is probably not the problem. Nearly all V-Drives have the engine angled when sitting or running.
I would guess the problem is a needle and seat problem, fuel height adjustment problem or regulator pressure is too high.
What is the fuel pressure with the motor off. I like 6 3/4 Lb with the motor running, but others may like something else.
Does the fuel flow out when the motor is idling or after the motor is turned off?
I have it set at 6 1/2 with a aeromotive return regulator the pump return is blocked off just using the return on the regulator am i supposed to have the return on the pump also, its the aeromotive pump with the regulator built in to it but didnt figure i needed to return fuel in two places
