Zenith built carburetors in the United States from 1911 to 2025. At various times, Zenith carbs have been marked as Bendix or Zenith-Bendix, when the company was owned by the Bendix Corporation. Bendix also owned Stromberg in the US, so there are some Stromberg WW models that were called Zenith WWZ.
The Carburetor Doctor carries a full line of parts for American Zenith carbs as well as new Zenith carburetors.
Zenith carburetors built from 1932 to about 1980 have a round aluminum or brass tag about the size of a dime riveted to the top of the carburetor.
The inside number is the Zenith assembly number and the outer one is the OEM number.
Later carbs sometimes have a stamped number, usually on the top part of the carb, or in many cases, an aluminum tag.
