This carburetor came with a project car and has been in long term storage. The throttle shafts are stuck and it needs to be gone through. I have never seen one quite like it, but I was told they are hard to find. I looked online to find as much info as I could to pass along.
Here is what I found so far:
The Holley 4000 series teapot looks like a teapot because the throttle body and the fuel bowl are mounted above the four throats, with the primaries enclosed in a cast-metal housing with two choke doors up front where the air gets in. The second set of throats is behind the primaries. The carburetor is called concentric because the design is centered around the center of a circle--like a bull's-eye target. There was a two-barrel version of the concentric Holley carburetor, but the 4000 series four-barrel teapot was the hot setup, and was really a pair of two-barrel carburetors in one unit. A primary pair of throats worked with a secondary pair that operated on demand determined by intake manifold pressure.
Asking $200 OBO shipping cost $20 or local pickup (Northern IL.)
