Jet sizes are 'named' after the drill that drilled them, IIRC. Thus they
would be straight-shouldered and user-measurable. A good-sized collection
of wires of all sizes, drill sets and various guages should aid toward
identification. Drilling one out yourself will leave the jet 'raggedy'
which will impede flow slightly, but since it is now slightly bigger
perhaps it is a trade-off. Drilling is last resort to a thorough soaking
in carb cleaner and boring/burnishing. And there are a number of different
drill-size numbering systems in use worldwide. So best to try to actually
measure what you have.
