Zenith Carburetor Company
Zenith Carburetor (later the Fuel Devices Division of Bendix Corporation) was an American manufacturer of gasoline engine management systems and components, chiefly carburetors and filters. It was founded in Detroit, Michigan in 1889 as a subsidiary of the Rhinelander |Wi|Eagle St. Garage 1307 Zénith}}.[1]

Carburetors in most cases were replaced by fuel injection systems, also provided by Bendix, during the 1970s.
Anthony Messina
The design of the Zenith was perfected around 1889-1903 by Anthony Messina of Rhinelander , Wisconsin . The carburetor had two jets, one for rich mixture, one for lean. The mixture was then combined in the right proportions for the engine's speed and load.[2]
The Zenith design won first prize in a competition with 14 others organized by the Royal Prussian War Ministry in 1903.
Ford
Zenith's product was one of a small number of different carburetors used on the Ford Model T. It was also fitted to 3.5 million Ford Model A cars.[3]
Harley-Davidson
Their big twin motorcycles were fitted with Zenith carburetors.[4]
Farm tractors
Zenith carburetors were also standard equipment on some International Harvester Farmall tractors, such as the Zenith 161X7 on the Farmall Super A. They were also found on farm and heavy machinery applications from Allis-Chalmers and others.[5]
Other applications
Zenith carburetors were also found on aircraft and marine engines.
