Here are some close up photos of my Solex/ Mukini Twin Carb set up.
They are 28-32DIDSA-A1 (Twin) as apposed to the standard carb 28-32DIDTA-9(M/T) or 28-32DIDTA-9(A/T)
They have smaller jets and a softer spring in in the depression camber that controls the vacuum secondaries.
I've included technical Info from a book that I have for those that are interested.
