I have been looking at the zenith 32ndix parts page in the manual.
what do the numbers refer to, as per diametre sizes.
eg. idle jet 45, main jet, 95/100/105/etc, air correction jet 240
I have some gas jet pilot drills and for the air correction jet, the appropriate drill size has 43 stamped on it.
I will upload a photo of the drills when I get to work later this week.

Does "Gas" and "Fuel Air mixture" untilise the same "Drill sizes" naming convention? I don't know, but if the hole in a jet is just a straight hole all the way through, then as long as the physical "Gas jet drill" fits the hole, you could then use it to make future Jets of that size.
If you could get a method of getting the stamped number on a jet to match a specific "Gas Jet drill" then you could make your own Jets to optimise your engine.
