How to Rebuild and Modify Carter/Edelbrock Carburetors
If you want to modify your carburetor-equipped vehicle for performance today, you can choose from three major carburetor families - Holley, Demon, and Edelbrock. While Holley and Holley-style carburetors like Demon have been popular for years with their well documented successes and quirks, there has never before been a book covering the ins and outs of the emerging Edelbrock line of carburetors.
How to Rebuild and Modify Carter/Edelbrock Carburetors reflects the emergence of Edelbrock carburetors as the predominant Carter-style carburetors in the market today. A revision of the best-selling title Super Tuning and Modifying Carter Carburetors, this book contains more than 300 black and white photos, illustrations, and diagrams, covering rebuilding, tuning, and modifying Carter and Edelbrock carburetors.
This book also features the history of Carter as well as the history of the AFB and the AVS since the purchase by Edelbrock. Author David Emanuel outlines carburetor types, gives a thorough look at carb selection and carb function, and offers detailed information on modifications, tuning, and rebuilding Carter/Edelbrock carburetors.
