Theres at least one computer program on the net where you put in the size of carbs, engine size, rev range etc and it gives you sizes for jets etc. Sorry I cant remember where I found the one I had.

I'm hoping that someone else that actually knows will answer this for you as I will have to go and read it all from a book, but if your still stuck tomorrow night let me know... While the book is great, I also dont want to give you bad info, in case I read something wrong or other misinterpretation...

Are they alfa DHLAs? If so what is the prefix on the carb, (DHLA 40-?)
They are harder to jet because they have a leaner progression phase for emissions. You need to go richer on your idles to cover that and stop the car from being too sluggish down low.

Yeah there is two general types the normal ones and the other is the emission control ones, I dont think they only were for alfa's though.
