Sorry for the delay, had airport duty today among other things so it has been a full day. As the Dr asked, where is the main jet and what is it? The F11 emulsion tube which should be fine for use. Here is where the Dr and I diverge for these cars from his post above:
If you are tuning for flexibility, I would think in terms of a 110 or 115 main to go with either a 27mm or 28mm venturi. For the air corrector, a 160 or 165, 45f9 for the idle jet, 35 for the pump jet and 40 for the pump exhaust as jumping off points. If you don't see a size on the venturi, get it out and get a good measure on the bore using a good set of calipers or a small inside micrometer.
Now for the part you will not want to hear. Typically the venturis come out as the Dr. described. However, I have had a few occassions where they did not want to come out easily and I wound up taking the carbs off the manifold and using a larger wooden dowel to hold the throttle plate open and using a smaller wooden dowel as a drift, I have had to apply a little bit of hammer love taps to the drift to get the venturi out. A light tap, then shift 180° across the bore, another light tap, and after a few taps, the venturi should come out using your fingers.
