Weber Carburetors by Pat Braden is the book we most often turn to as a reference on Weber carburetors. If you call our Tech Line, chances are we'll look the answer up in this thorough reference guide.
This book does an excellent job explaining the basics of carburetor design and theory of operation. You will learn how the different circuits interact to determine the mixture under various conditions. The section on emulsion tubes is worth the cover price alone.
The book begins with an interesting history of the company including early racing efforts. The heart of the book is dedicated to explaining the function of carburetors in general, and Weber carbs specifically. Detailed sections cover teardown and rebuilds of several specific Weber models, including the DGAV dual down-draft, DCOE dual side-draft, and 40 IDA triple. The final section details Weber conversions for MG, Alfa Romeo, and Small-Block Chevy. Several tables in the back of the book cover specifics on jets and emulsion tubes. Easy-to-follow instructions, original factory drawings, and dozens of clear black & white photographs illustrate everything. 176 pages, softcover.
