Primary metering rod and spring change in 5 minutes on 2 carburetors. Now that is a very smart design.

Yes indeed. I really like AFB's. Only one I've ever owned before now was on a '67 Buick 340 that I pulled from a salvage yard Gran Sport and transplanted into my '64 LeSabre in place of the worn-out 300 2-bbl. A direct bolt-in. That was in 1976.
