Good score!
The carb you got is about 212cfm at 1.5" HG, and its just the primary half of the 4100 Autolite I mentioned. When I ran the 4100, gas mileage was at least as good as the B/BC/BV 1bbl Rochester carbs. That 2100 Autolite is such a good carb it was used from 1957 all the way into the 1980s.
Im not a Monojet fan either, I guess when they're ok they're ok but when they act up they are bad news.
