Ok, this discussion was started on another thread, but to avoid getting off-line I figured I would start a new one.

about what sized carbs should be used on a 3.2 SC short-stroke. As I am currently an owner of this type engine and considering adding carbs, I am very interested in other people's thoughts on this. Jamie's thought was that 46mm's should be used.
Ok, just to drag Bruce Anderson in on this, he makes the recommendation for this type of engine to go with the Weber 40 IDA-3C. His point is illustrated through a quick calculation of optimal venturi size of a 3.2 displacement giving a range of 38.5mm to 43.75mm.
Does anyone have any practical experience with either sized carbs? If you do, I would be very interested in what your jetting set-up was.
