so ive got a set of aftermarket 46s here and upon setting them i realised that the plate that plate that covers the jets internally have a code stamped on the top of them now my question is the 46 s have the code R1-2-1 and the other carb has R1-2-2 to the eye look identical , so ipulled my aftermarket 44s apart and the numbers matching being R1-2-4. so does anyone know what these numbers are and can the mis match work as a pair
thanks luke
