Dialing in a Carter AVS

Not relevant to your carburetor issues, but there's not a damn thing wrong with your pappy. Back when he was doin things, there was so much zinc and phosphorus in motor oil they just cranked new cars up right off the assembly line and drove them out into the lot. Precious little time for break in on those assembly lines. There was hot testing on SOME engines, but nowhere near all. Most of them were busted right off once the car was completed. So in a sense he's right. At least the sens of how things used to be.
