I DON'T have experience with that carb. The simplest thing would be to buy a rebuilt kit for it, take it off and follow the instructions. I doubt that you need to be a rocket scientist to do it. Here a kit would cost you about $30. Can't do better that that.
It might be a good idea to start with what you have and drive it around some. You might like the nature of the car the way it is? You can always start modifying it later.
Let me know when you get to the Webers. There I can help you alot!
