This weekend I rebuilt the original 4gc from the car. It had a 4gc from a cadillac on it, sitting on the original throttle body that was improperly jetted and running extremely rich.
On the throttle body the secondaries were seized and had been for a while. Rat turds and all sitting on the secondary butterflies.
Mounted up the rebuilt carb and realized secondaries wouldn't open. Unbolted and played around and found if the carb body wasn't pushed all the way back towards the firewall while bolting that the secondaries would hit the manifold and could not open. Obviously why they seized to begin with.
Car is running way better with the original carb!
