    are idle air tubes neede on end carb?


    Rebuilding a rear carb for a 66 Pontiac and the venturi cluster is missing the 2 outer idle tubes. Since it is a end cab, are they needed? Any thoughts?

    Welcome to CHR!

    Normally only the center carb has the idle circuit active, with the front & back carbs providing secondary/WOT input. If it's OEM I'd look at the front carb for comparison.

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
