My 2.4T with a PMO Weber conversion came with the following jetting

Weber 40 IDA 3C
Main jet: 130
Idle jet: 55
Air correction jet: 180
Emulsion tube: F1
Venturis: 30 mm

If your carbs were set up for a 2.7 you will probably have to reduce main jet size. Optimizing jet sizes is a lengthy process but worth the effort. Just went through the whole process and am very happy with the outcome.
