4150 carb guru's......pouring venturi's!!!

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?

sounds like a float problem.

Never had one do it in the secondaries but in the primaries it was a blown power valve...Now I just block them-off...

It's weird. No power valve, and I've ruled out the float by changing the bowl. If it were a pressure issue, I'd think the front would be leaking as well.

is fuel running out at float level check hole with plug removed?

throw it in the trash and replace it with an Edelbrock 750m

You seem pretty sure it's not the float. There is a plug instead of the rear power valve, right? Wrong gaskets maybe? Can you swap the rear metering block to the front and see if the problem moves?
