Intended for instructors serving the occupational needs of disadvantaged and handicapped students, this curriculum guide contains 16 units for a small engine maintenance program. Its purposes are to provide minimum skills of students already mainstreamed, and provide vocational instructional materials for the modified classroom. Teachers should adapt these self-paced and self contained instructional materials to suit teaching/learning situations. The 16 units cover these areas/topics: job opportunities, safety rules, small engine tools and their uses, small engine parts and their uses, fuel selection and use (two-cycle), inspecting and servicing spark plugs, cleaning and inspecting cooling system, servicing air cleaners, cleaning and inspecting crankcases and exhausts, changing oil in four-cycle engine, checking carburetor, preparing for carburetor adjustments, adjusting carburetor choke and high speed load valve, checking ignition system, and starting and operating small engines. Each unit contains these sections: (1) unit objectives and self assessment statements; (2) introduction (motivational statement); (3) description of tools, materials, and equipment; (4) steps of procedure (explanation and illustration of given skill); and (5) student evaluation (true-false, identification, or steps of procedure).
