    I have my 715 Holley apart and I need to adjust the rear float. Can someone give me the procedure for this adjustment. Does anyone have a rebuild instruction sheet they can help me out with. The rear float is at 1/2 inch from the top of the bowl and I am trying to adjust it to 3/8 before I reassemble the carb. Any help would be appreciated.

    Thanks
    Bob S.

    Hi,
    The primary is supposed to be 3/8" from the top and the secondary
    1/2".

    Bob,

    IIRC, you need to turn the bowl upside down and measure from the top inner surface of the top of the bowl to the top of the float. The force of gravity is enough to seat the needle so you can get an accurate measurement but not so great as to damage it.
