I never saw there being that much to a carb, other than wanting a smooth delivery of fuel to the engine, as is every other fuel delivery system. It is actually one of the easiest parts of an engine to rebuild, all you really need is a table and a lamp, and a few of the simplest tools.
I started off with a little Suzuki motor bike, then a Honda, neither one of which was ever any real problem to fix. If changing out the gaskets didn't help then change the dam jet, about all you could ever do to one anyway.
My brothers little 396 was the only engine that ever scared me. He used to cuss the ones in front when we were going through town for driving too slow. That thing idled about 45 and he'd be riding his brakes trying to slow it down and not have to drive over the one in front.
Even when he sold it I was walking around behind them asking all kinds of dumb questions, "Did you ever get that second gear replaced?" I heard him tell the guy, "He don't want me to sell it". My father gave us his old station wagon and we couldn't get it to scratch gravel after backing it downhill and dropping it into low gear.
I bought a 63 Chevy pickup with a new rebuilt 327 and a 4 barrel, you could see the gas gauge drop anytime you pressed the pedal. I used a 2 barrel off a 64 Impala I had from school
U could go on forever and really never come up with much more than change the gaskets and change the jets, tune it right and enjoy, and of coarse, set the float
