Weber IDF's work well, but some people prefer Dellortos which are no longer being made but can be found used. Many places sell Webers, Aircooled.net and CB Performance included. They can help you with size and jetting. Few people recommend the Bosch 009, the 050 is preferred. The stock distributor will work too. The Mallory Unilite ($$$) is probably the best for the application. The facet pump will do the trick but is a noisy little devil. Mount it on rubber isolators. Be sure to get the model that delivers 3.5 psi as Webers need only 3-4 psi.
Do a search in this forum and in
http://shoptalkforums.com/ (Type4rum) for Webers, carbs, fuel pump, distributor, etc and you'll find a bunch of good info.
