               American Wire Gauge #20AWG is 0.032 inch, but 0.73mm is 0.287 inch (0.032"=0.81mm). I caution that there are at least another half dozen wire gauge standards in the world, so ????
Your numbers look like "happy numbers to me. I like the way they match my own notions/numbers I have come to accept. Real close match I say. Using pin gauges and calipers, there is probably always some doubt in the 3rd decimal place.

Subject: My carb. jets measurments notes.

Found them in the shop!!!
Here are the #s I have written down.
Idle ......part # 9N 9596....did not have a drill this small, but used a 20 ga. piece of stainless wire. !!?? Fits real snug.
Econo.....part # 9N 9914... 0.046
Main.....part # 9N 9533....0.042--0.043
I have used these #'s on the last 3 carbs. I have overhauled, and have had real good results on all of them.
I buy these carb. jets from "Just 8Ns", due to being able to get them in singles, with the part# on the label.
I know that with this system, I cannot know what mod. M/S carb., it is jetted for, but It is my thought that, If they work good this way, with NO returns, and NO problems.......WHO really cares!!!???
BTW: If you can tell me what the sizing would be for 20ga. wire.....let me know......LOL
If I remember right the package the wire came in, had .73 MM, written on it, along side the 20 ga.
Hope this helps.
