Suck or blow through application.?
The problem with using only one WEBER, is trying to get enough fuel in the emulsion tube chambers for proper transition from the idle jets to the main jets.
My NA 12A rally port with a single 45COE has this problem. I partially solved it by getting the thinest emuslion tubes and experimenting with the bleed holes in it, and also getting the longest accelerator pump rod.
A single on a rotory is too small!
That is why you see many old European 4 cyclinder engines running two 40 or 45DCOEs.
Figure; my old Alfa 1290cc autocross engine had two 40DCOEs with 32mm throats while my RX7 had a single 45DCOE with about 40mm throats.
The Alfa had less restirtive carbs with a greater fule supply.

you'll need a carb hat and i believe you also need to change the floats from brass to rubber (or vice versa), beyond that, i'll defer to the experts. contact either 680RWHP12A or Wackyracer on this board those are the two best sources of knowledge i can think for turbo carb'd rotaries and IDA's (respectively).
