Okay. I'm confused by this carburetor.
The stock BBD needs gaskets and an overhaul, and was leaking quite badly.
The car came with a Holley intake and a 650cfm vacuum secondary carb, which I had put a rebuild kit into a couple years back.
I decided to put that on today, hooked up to the stock engine pump that had been running the Carter fine.
It pumped up and started gushng fuel out of all the primaries. I checked the first levels and they're set up sensible.
I pulled the primary bowl off, plugged the secondary feed, held the float up and it shut the fuel off on crank, making about 5psi.
I pulled the meeting block off and tested the power valve, which isn't split and holds vacuum.
Anybody else had this weird issue with a Holley before?
