Delve into all aspects of Holley Carburetors with knowledgeable instruction from this guide, which shows you how to disassemble, select new parts, rebuild, and calibrate all of the major models.
Veteran engine-building expert and automotive author Mike Mavrigian guides you through each important stage of the rebuilding process so you have the best operating carburetor for a particular engine and application. In addition, he explains carb identification as well as idle, mid-range, and high-speed circuit operation, specialty tools, and available parts. You often need to replace gaskets, worn parts, and jets for the prevailing weather/altitude conditions or a different engine setup. In an easy-to-follow step-by-step format, Mavrigian shows you each critical stage for cleaning sensitive components and installing parts, including idle screws, idle air jets, primary/secondary main jets, accelerator pumps, emulsion tubes, and float bowls. He also includes the techniques for getting all of the details right so you have a smooth-running engine.
