Foreword
Before attempting an engine overhaul or a tune-up, it is necessary that your shop be equipped with proper tools and mechanics who are thoroughly familiar with Briggs & Stratton engine design. This book serves as a guide for the various steps necessary to do a complete and satisfactory job. Use plug gauges wherever possible to eliminate doubt and ensure all parts are within rejection sizes. Illustrations identify specific repair procedures even when they do not designate a particular model.
