components, the books mentioned above can't help you. When it comes to tuning the ignition and the carburetor on a performance engine, including how the different adjustments affect each other, there has never been a single source of reliable, easy-to-understand information.

Now there is. This book takes you through the various steps in the process of adjusting your ignition and your carburetor, including the very important sequence in which they must be done. It deals with questions like: If I turn the idle mixture screw out, and the engine responds like this, should I then turn the screw more and in which direction? How do I ensure absolutely optimum jetting of my carburetor? How do I create a distributor curve that optimizes ignition timing at idle, part throttle and wide open throttle?

All the questions you've come across when trying to adjust your engine for performance are answered here. The simple step-by-step instructions in this book only require your time and effort. Techniques like plug reading and using a vacuum gauge are described in detail. Only standard tools are needed-no dyno or anything like that is required.

In addition to engine tuning, this book contains advice on choosing the right parts, to ensure that they will complement each other, not work against each other. Plus there are many tips on troubleshooting and on winning races. Finally the book also contains special tuning tips for boat engines, including a chapter on the differences between a car engine and a boat engine.

This is the last book on engine tuning you'll ever need.
