Re: 3 carb setup question-Idling WAY too fast
Possibly. I actually closed the idle mix screw in the secondaries to see if that made any difference (it did not). I even went so far as to close all three idle mix screws, with no effect. I don't think that i'm even using the idle circuit. According to the Offenhauser instructions, it does seem that all three should be running an idle circuit, since it gives instructions on how to set the mix. Perhaps the loss of vacuum from the two new holes in the intake isn't allowing it to function correctly.
