the factory tuning manual is pretty good. Most of the stuff that people who
are really familiar with webers have in their heads do not appear in any of
the manuals I've found. I don't know why that so--some of it seems pretty
straightforward, though I can never remember it and always have to ask. I've
found Bob Yarwood (the same guy that has the bearings) to be a fount of
information on carbs.
there's some good info in the tech pages of www.webercarbs.com though they
are a little disingenouous about tuning--they want to charge you to "set up"
your carbs without having your car. that's bullshit. They also recommend the
Carter pump (which is what I use) with NO regulator which I've found
delivers about 6 pounds--way to much pressure. They don't like the holly
pumps and hate the facets.

Hi all!
I agree with Tony -- I have the Braden book as well, and have greatly
benefited from reading it. It discusses the basics of carburetion
(including an exploded diagram of an SU carb, of all things), Weber
construction, troubleshooting, repairs to the various Weber models,
modifications (compression, ignition timing, volumetric efficiency,
manifold selection, linkage geometry and Weber selection), Weber
conversions, and production specs. There are hundreds of clear
photographs and diagrams -- (the pages of carb/manifold combination
diagrams are great!).
I found mine at Half Price Books for $5.98 several years ago. You might
check www.half.com or Amazon for availability
Good luck!
