    I need the real story on the location of the pilot and main AIR jets which are under the little cover.

    The service manual picture on page 124 and carburetor parts breakout on Page 126 differ as to which is which. I believe my idle issues may be related to the correct orientation of these jets.
    Thanks.

    Pilot air jet = larger size air jet = forward-most hole under diaphram

    Main air jet = smaller sizer air jet = center hole under diaphram
