Having said that, if you copy an old 850 DP you should be fine. Put an 028 in the top hole, blank in second, 028 in third and blank in the bottom. That should work well enough to get you going. You can play around with it if you want but I doubt you'll tell any difference. I've tried a bunch of different emulsion combinations over the years and never really noticed any difference.

If you really want to talk about emulsion jets then Tuner is probably the one guy on the internet who knows his stuff.


Nothing like insulting lots of smart guys that DO understand emulsion and other passages within a carb just because YOU don't..........Maybe we should bash your products mister wise guy and didn't you write a book that had a "Carb tuning" section..........Maybe EFI is best for you because you can push keys, make TONS of hp on your little optimist dyno but never post em.............THIS reaction from you really pisses me off I must say............... down tsk
