    Tuning question.
    i'm using a FAST AF meter to tune my carb.
    if i disconnect the secondaries, what should i expect?
    will the primaries run lean at high RPM.
    humm, it was born as a 350-2 barrel.
    i'm working on understanding the different circuits and tuning them.

    If you disconnect the secondaries the carb will not flow as much air so you won't need as much fuel. I did this on my 1000 HP Holley carb because the car ran to fast for the class and it never became a problem. It just made me mad that I spent $8500.00 on a motor that I had to slow down. Just my two cents worth.
