I can't count the carbs I rebuilt. It really wasn't too big a deal. Not sure if they still do, but they did have a schematic drawing with all the parts pointed out, and if you could tear it down in sort of a line and get it all layed out, then just go back across putting it back together using new parts and gaskets until you had it back together. The main jet was probly the main thing to it, and it usually just dropped out after removing the pin. There were also tiny chrome b-b type balls that I'd use new ones, they usually just dropped down a hole somewhere. Adjusting the float wasn't difficult either, they included a tiny cardboard ruler that you'd use once right side up, then flip the carb upside down and measure the other max, adjusting a bendable tab to set it to the correct level
The trickiest part wasn't usually in the carb itself, but in the linkage connecting everything together such as the auto-choke connector, gas throttle, springs etc.
I started out on motorcycles and then just naturally went on in to cars. It may seem kinda daunting if you've never done one, but after doing it once or twice there's really not much to it.
