This is a late Model A Ford Zenith 2 carburetor made by Holley of Detroit for Ford back in the day. Its for indented fire wall cars and trucks make in late 1931. Original Zenith 2 core, cleaned, painted correct flat black gas proof paint. Passages all cleaned, threads and jets checked, parts replaced as needed. I have used as many original parts as possible to keep cost down and  maintain originality. It has a new teflon seat original style float valve and idle jet and second well. It has all new screen and drain cock for original side filter. After rebuild it was test run on my 1928 tudor, nice acceleration and idle. This carburetor was tested on an early car so side bowl was not installed, but I have included a screen, gaskets, and petcock for the side bowl when you install it on your car. Please look at photos closely and feel free to ask questions, only ship to USA address. Credit given for good cores. A nice running, and RARE carburetor.
