    Hi all,

    I am working on my V12 carbs (2 carb modell, carb type D5TH. One detail I found: Burlen have “AUC1170 green” as correct for this carburettor in their list. In a copy from an old SU book (see jpg posted under general technical info) it says 1166 white is correct for the 2 carb D5TH and 1170 green is correct for the 4 carb D4L

    1170 green has thinner wire, 0.9mm thick, so weaker spring
    1166 white has thicker wire, 1.1mm thick, so stiffer spring

    comments welcome
