Weber Carb set up

Hi Guys,

I have installed a sport exhaust and perf camshafts to my 1974 GTV 2000. So now it needs rejetting to work properly, and I'm having issues with the progression and transition to main jets. I understand that bigger jets are needed, but it seem emulsion tub also need to be changed as then engine shutters between 1400 - 2100 rpms. From 2100 rpms, engine works very well with 138 main jets, 200 air jets, and F9 emulsion tube (with I suspect need to be changed to give more fuel earlier). The ideal solution would be a rolling road and see where I'm rich/poor, but I haven't found any specialist for the moment.

Has anybody have installed alfaholics (CatCAMs) P07 & P08 cams, and what fuel/air jets and emulsion tubes are needed? All suggestions are welcome
