Other books you might consider are "Weber Carburetors" by Pat Braden and "How to Build & Power Tune Weber and Dellorto Carburetors" by Des Hammill.
My 1700 Crossflow has the Kent 244 cam and head porting. The Weber 40's have 120 Main, F16 Emulsion, 165 Air Correction, and 50F9 Idle. Haven't checked to see what the Choke size is. To my somewhat uneducated foot, it doesn't have any real flat spots (although things don't really get interesting until about 4000 rpm) and starts easily.
I've been told that changing things on Webers can be a slippery slope. Good luck!
