Zenith Carburetor

Model A Ford Zenith Carburetor

Model A Ford Zenith Carburetor

The Model A Zenith carburetor was fitted to all Model A production from 1928 to 1931. They were manufactured by Zenith, Holley and even Ford themselves, although the Ford version is quite rare.

We offer the complete range of spare parts for these carbs, which are all compatible with the three manufacturers.

We also find these carbs with different names on the castings. I have two of them with Kayce cast on the side. We understand that these were popular in the European market. Nevertheless, all the replacement parts fit them.

Lucas Ethanol Fuel Stabilizer E62A-40576

Safeguard Ethanol Fuel Conditioner. One bottle treats up to 302 litres of fuel.

1928-31 Float Valve Reseating Ball A-9564-X

1928-31 Float Valve Reseating Ball A-9564-X

If the float valve on your carburetor doesn't shut off when you shut off your motor, the needle may not be seating properly in the housing to properly shut off the flow of fuel.

Since most carburetor float valves are now the Viton tipped style, you can no longer tap the needle with a hammer to re-seat them.

Remove the needle from your float valve body and place the ball in the seat where the needle seats. Give it a light tap with a hammer and you've now created a new seat for the needle to seat and properly seal.
