       INTRODUCTION

      During the 1950s and 1960s, the Holley 4-barrel carburetor established itself as the clear leader in high-performance operation because it provided precise fuel metering in low-, mid-, and high-RPM operation. Also, it was a modular design that was easy to tune and had a wide range of parts. The Holley 4150-series, or Double Pumper, carburetor distinguished itself during the muscle car era because it had an accelerator arm pump on both float bowls, so if the carburetor were used for aggressive acceleration or wide-open throttle, it would deliver all the needed fuel into the engine when called upon.

      Although the basic architecture of the Holley 4-barrel carburetor has remained largely the same for 60 years, Holley has offered several different series of carburetors, such as the 4150, 4160, Avenger, and Dominator. And of course, many different carburetor models exist within these series. In this book, I review Holley carb styles, models, features, and sizes, so you can accurately identify your particular carburetor and its parts.

      Many classic cars, muscle cars, hot rods, street rods, and competition cars are equipped with Holley carburetors. If you have an OEM Holley carburetor, it is most likely 30 years or older. Over time, gaskets deteriorate and bushings wear and possibly leak, metering blocks and jets are exposed to contaminants and become plugged, jet needles and jets wear from use and no longer meter properly. If you have an aftermarket carburetor, it may be newer but a lot of usage may require a rebuild. Or possibly, you СКАЧАТЬ
