Carburetor Technical Information
Holley 1900 Series 1 Barrel Carburetors
Holley used '1900' designations for several different series of unrelated carburetors.
The Holley 1901 was a 'Concentric' carburetor, similar to other 'Teapot' carbs - more information
It had nothing in common with the 1904/1908/1920/1940/1960 series which featured a detachable float bowl. The 'Visiflow' series of carbs used a glass float bowl, but were otherwise similar to other 1904 carbs.
The 1909 carburetor was another completely different carb used on AMC and Ford applications in the 1960's, sometimes interchangeably with the Ford 1100 carb.
The Holley 1945 and 1946 carburetors were a new design in the 1970's. They were used on Ford 4 and 6 cylinder engines into the 1980's, and on industrial applications well into the 1990's. The 6145 was a computer controlled, feedback version used in 1985 Ford 4 cylinder cars.
