I've got an 4150 that was older, but new. I put a full holley kit in it, just to make sure the gaskets were perfect. It's dumping fuel out the boosters. Not a drip, but a steading gush. I've changed needle and seat 3 times, no luck. It's just the secondary. I even changed the bowl, just to make sure it wasn't a float problem. It's a 440 with a stock replacement carter pump, not a high pressure unit. Fuel does not come out the vent. Any ideas?

From what I understand the spring stiffness (plus the passage dia's) controls the psi and the lobe reloads (compresses the spring) so I'm wondering if an assembly line guy accidently (or on purpose ) put the wrong spring in there as it was going down the line

if your needle isn't seating properly you can have this problem. i know with my carb the jet extenders can cause interference with the floats also.
