    As far as I can remember there are only 3 kinds of those MD needles, concerning the business end. There are the short ones that control air, the long ones that control fuel and the left-hand thread ones that correct the backwards rotation for rich -lean on the short ones. And then of course there is the outside end that varies to accommodate cowling etc. Knowing these features may help with your search.
