    Weber Jet settings for 71T ex UK car

    Hi guys I've had problems with my 911T 1971 model not idling properly, but is great above 3000rpm.

    After much consideration checking other basic facts we have just pulled the Weber's off and found what we think are incorrect jets and modified emulsion tubes. The Webers have the following identification:

    40 IDTP13C (with 5107 below) and
    40 IDTP13C1 (with 5232 below)

    Can someone suggest the correct factory sizes for:

    Venture =
    Main =
    Idle =
    Air =
    E-tubes =

    and who they can bought from ? Finally if there is a source that this information is freely available from ????

    Thanks in advance.
