Need to rework carb needle, seat and float. Also why you want to keep vacuum petcock. But of course in a working order.

Get you a hand held vacuum pump. You need it for old stuff and bleeding brakes.

I'd think very seriously about trashing the hypercharger, those things are notorious for trouble with vacuum leaks. It would explain a lot of the issues you are having.

The kits come with extra gaskets/o-rings for different series of the CV plus a few I've never figured out

Photo# 3 - take that o-ring off. The mixture screw should have a small spring next to the threads, small flat washer and smaller o-ring, in that order. The tiny o-ring usually stays stuck up in the carb body. Those 3 parts do not come in any kit that I know of and have to be purchased separately. Don't worry about them so long as they are all in correct order when assembled.

Shake the bowl. You should hear a distinct rattle. If not, more cleaning is required...
