Designed to assist students in developing the skills required of professionally certified outdoor power equipment technicians, this book features operation, troubleshooting and service information that can be used to maintain and repair commonly used outdoor equipment, including: lawnmowers and garden tractors, snow throwers, leaf blowers and string trimmers, chain saws, and more! Comprehensive in scope, Small Engines for Outdoor Power Equipment begins by acquainting students with shop safety, tools and basic service information. Following exposure to "the big picture" of small engine operation, students are then introduced to the specifics of the ignition system, fuel system, governor and throttle control system, lubrication system, cooling and exhaust system, manual starting system, and the electrical starting and charging system. Both two-stroke and four-stroke engines are covered in detail. Small Engines for Outdoor Power Equipment also features step-by-step photo sequences to illustrate service techniques and provides students with an opportunity to "test" their knowledge by conducting a failure analysis and successfully rebuilding a failed engine.
