fuel exiting vent tubes
Been getting a little seat time with the new 463 and have noticed that if I get on it pretty good fuel will exit the vent tubes and then travel out the back of the shaker. Running with open carb at the present because I haven't figured out exactly what I want to do about an air cleaner setup; very limited space with the QF950 sitting on a Northwind intake with a 3/4 spacer. I can squeeze an 11x2 on top but that hardly works for street driving, certainly won't work at the track. My shaker is attached to the hood and can be removed pretty easily so when the car is ready for the track I will probably do that and run a tall air cleaner up through the hole in the hood or maybe a velocity stack. Anyway, I assume the fuel is being pulled from the vents because there is a low pressure at the back of the shaker? And as I get to a certain speed plus the effects of acceleration causes the fuel to leave the carb. Anybody else ever experience this situation?
