1920

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.
 
The 1920 carburetor is identified by it's LIST number, which can be found on the top of the main body, just behind the float bowl. Holley carburetor numbers may be listed as R-1185-1A, with 1185 being the list number and generally can be used to identify the correct carburetor kit.

Our catalog includes carburetor kits, floats, thermostats, choke pulloffs and other carburetor related parts.  All parts that we have available can be found in this catalog. We often add new parts, so check back every so often.
