Holley carb loses prime to primaries but not secondaries - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Im tying to get one of my trucks going. It has a Holley 750 double pumper. It ran fine about a month ago. I figured the carb would be dry and it would take a while to get it started, but even when priming it, it wont start. I took the air cleaner off and when i work the throttle by hand, gas squirts from the rear secondary nozzles, but not the front primaries.

I had the same issue with another holley 800 double pumper, and i figured it was time for a rebuild when it did the same thing. I ended up swapping it as someone had milled the choke tower off it, and i wanted an electric choke. Now this carb is doing the same thing.

Again, the 750 was running fine the last time i ran it!

Ideas?
