Although my car is running well, I'd love to have a great reference for maintenance/tuning of my sidedraft Webers if I need it. What manuals are the best out there?
I agree that the Passini books (later published as a single edition) are a challenging read. I think his stream-of-consciousness style was just that: he probably recorded his thoughts and then had them transcribed. As I puzzled over his "writing" I decided that learning to decipher Passini was a rite-of-passage---there really is a wealth of Weber specific information there. I put the Passini book up there with David Vizzard's "The Theory And Practice Of Cylinder Head Modification" which, alas, is also long out of print. A local library may be able to obtain the Passini book on inter-library-load.IMO the best books for getting a good understanding of Webers are the two by John Passini but they are long out of print and Passini has a strange writing style.
