OK, here's an assortment of main jets. One on right (with the groove) is marked 19 and seems about .032 dia. Next is a 23, about .040. Finally, a 24, about .042.
Of the 3 donor carbs, one is an adjustable main jet. The other two just had the plug.
It seems I recall (from somewhere) that the 23 and 24 are the usual sizes for fixed main jets. But then, why would the odd man be smaller? I would have expected it to be bigger, then control things with the adjustable jet.
I have the capability to ream #19 out to .050, but thought I'd get some input from you experts before doing so. It's tough to put the metal back!
