Lynn;  Before I just tore into the carb, I was looking for a drawing, also the sizes of the emulsion tubes, mains and air jets.  I have never had a Weber apart, so didn't wish to plunge ahead blindly, seen many bad results by this procedure.  JohnD
The numbers are marked on the jets and tubes. Nothing to it. Jetting is based on flow rate and that is controlled by choke size. (the choke has the size molded into it and it is removeable also). Any size you want is available. Most of the Mazda hop-up outlets have the parts and jets, and can be ordered through most foreign car parts stores. BAP-Geon and the like. There are some changes to make for rotary use. But a good outcome for up to 250 HP.
 
There are many Weber books that show all you need. I have been using one since 1980, if you have any problems.
