    Hi. Mine is standard and has Dellorto PHBH 26mm on it. If you require the spec of the carb I have a handbook with it in.

    It should have been a Dell'orto model:

    Type: PHBH 26 BS

    main jet: 88

    needle jet: BN266

    needle: X5, 2nd notch,

    idle jet: 48mm

    Gap at the slide: 4mm,

    gas valve is normally: 200

    and choke us normally: 65

    For first TX311 model from 1986,

    taken from German Trialsport Magazin, issue 120, March 1986.
