thats what i figured.
i actually like the design of my afb more then the quadrajet. ive been out and about and noticed at cruise my afr was super lean, but i was going down hill at like 1000 rpm and although that scared the $h1t out of me, i realized the motor wasnt working at all...
ive been with my gf at the park and changed rods before and or adjusted the mixture screws.
my big ol 1980 suburban with 33 inch tires is getting 8.5 mpg when i was driving 22 miles a day 35 mph tops and a few 25-30 mph zones. at times when im putting at 25-30 mph my afr goes lean in the 15.5-16 afr but as soon as i start going up slight hills it drops to 14 ish.
i know the carb pretty well, and i dont feel the mpg im getting is bad whatsoever. and i bet if i went to a qjet id have the same mpg.
