Just did a simple rebuild on my Holley 600. Problem; upon cranking what would cause the secondary bowl to fill fine, but the primary does not fill at all. I removed the primary bowl to recheck and everything seemed fine. Needless to say, I'm not able to idle due to not being able to feed the primary bowl.
Needl is stuck in the seat or the float is set to high and jammed against the bowl.Also...Line feeding primary bowl is plugged for some reason.
