    Weber 40 IDA jetting

    Hello,

    My 2.2 T from 1970 does not have classical Zeniths but a pair of Weber 40 IDA.

    I am going to clean/rebuild them, but as they are not standard on my engine (I suppose they come from a 2.0 engine) I have a doubt about the jets...

    Can you suggest me the good jets/venturi for street use on a 2.2 T engine ?

    Weber Set Up

    I have had good luck with the following setup. This should work well for a 2.2T or 2.4T
    Chokes 30
    Main jets 130
    Air 170
    Idle 55, you may also try 60's if transition is not smooth

    Thanks to every body.
    I have a big doubt, may be my venturis are 27mm, from a 2.0 T ... I will check this Week-end.

    Zaza,
    Stock venturis are 27mm on a T. If you want 30s btw, I have a set.
