I have a strange situation here.
I have a stock 360 in a Duster, it has a Weiand 4 barrel intake and a Holley 600 single feed VS # 1850 carb. The Holley was rebuilt a couple of years ago but the car has been sitting. I've had this car here since 2007 as a project with my brother in law who lost interest in it years ago.

This car will start and run, but within moments the engine starts to sputter and fuel starts puking out of the vents, then out of the boosters. Of course, it stalls and won't restart until the fuel evaporates in the intake.
Float level too high?
I adjusted it and it still does it. I pulled the carb apart, soaked it awhile, blew out the passages and put it back together with a new power valve and needle valve.
It still puked fuel. I tried another carburetor, a Rebuilt ThermoQuad. Yeah, that one pukes fuel too.
I have no gauge to test the pressure but the inline fuel filter isn't getting full or bulging, it looks fine.
I'm going to try another carburetor on this engine tomorrow, maybe the one from Jigsaw. I know that one is fine.
This is weird though. I've never dealt with this before.
