Default Re: Holley 22XX Series Carb Stuff

The thin sheet metal "cover plate" for the hic item never had a gasket, it won't "seal" the port at all as the "intake" point for the valve when it actuates is within the carb body, ...trace out that circuit with compressed air or carb cleaner. The cover just retains the actual valve element in position over the port.

The seal for the hic is/was a very thin composite cork ring that fits down in the counterbore for the valve pintle. The round hole where that seal fits is what ya need to plug off to prevent a vacuum leak if the valve itself is gonna be removed.

You got the "idea" in my subliminal message about "off road" mods!!!! But in reality , the "emissions" schnizz izza federal thang...always has been.
Are yawl ready??? If not here's some training ya might need to prepare:
