Holley 1920, 1-barrel Carburetor Rebuild Kits and Parts

The Holley 1920 carburetor is a one barrel downdraft carburetor with an aluminum throttle body, zinc float bowl and metering body. Some 1920 carburetors had a glass float bowl and the glass and zinc float bowls are interchangeable. The metering block contains the main metering jet and accelerator pump check valves. The accelerator pump can be a cam operated, or a spring type. The cam type will use an accelerator pump with a flat stem, while the spring type uses a round stem type of pump. The 1920 generally used a Nitrophyl type of float, which should be changed at each rebuild, but unfortunately the 1920 float is no longer being produced.  We do have a NOS 1920 float that fits some of the 1920 carburetors. Holley 1920 float weights.
