Although the ede 750's and the last of the carter 750's were both made by weber, and both came with the same jets and rods, they did not provide the same a/f ratio when run on the same motor back to back.
Subsequent disassembly and inspection showed definite differences in the calibration with the air bleeds and clusters.

No way would I assume that the jets for an OE MW carb would be optimum for an aftermarket similar version of that model carb just because the throttle bores and venturii are the same size.
In the same way not all 750 Holleys are supplied with the same jets, or would require the same jets, to achieve equivalent a/f ratios on a given engine combo.
