until I could get a big Carter AFB
Boy, does that bring back memories. In 1966 I bought a brand-new Carter AFB (Buick, by the Part Number) and stuck it on my '57 Ford 312. I kept that convertible from 1965 until 2005, auctioned it and my folks' place that year in November. The Ford still had that AFB, and ran great. I probably kitted it twice in that 40 year span.
Our troller / original poster has failed to get us going on engine debate here. No one has mentioned the real difference : 2 strokes scream, 4 strokes growl. I'm happy with either, on a given day!
Cheers,
Dave Olson
