The Holley 1920 carburetor generally used the Nitrophyl type of float and should be replaced anytime you do a carburetor rebuild. The Nitrophyly float tends to absorb fuel over time and can cause the carburetor to flood over. Unfortunately these floats are no longer being produced, but we were able to obtain several of these floats.
