Bill,
Heer is an example of my initial setup. I am not saying that you should have this setup, this is just to provide you with an idea of some of the items and numbers that people are asking about. You may end up with similar parts to this list, but i would not suggest replicating this as it was setup for racing.
Webers are easy to take apart and configure. If you do end up needing different jets, holders, chokes, etc. Pierce Manifold is a good source, and they are in CA. When you take the screen off there will be two sets of jets there, two for each barrel. The large screw head is for the primary jet and the small one is for the idle jet.
