I recall around '79 that Carter came out with the 9801 (I believe it was), which was an aftermarket replacement. I loved that because it came with an electric choke. Ah, the days!
Yes, a Chrysler throttle arm and a Chevy throttle arm.
800 cfm rated, small primaries, & the electric choke that work’s great! Carter called it there “ Rochester replacement carb.”
I don’t know what the deal was with the QJ back then? Must have been something.
