This student manual, part of a small-engine repair series on servicing fuel systems, is designed for use by special needs students in Texas. Information covered in this manual is considered to be the minimum that students need to know about fuel systems in order to get small-engine repair jobs. The manual introduces students to small-engine fuel systems with numerous illustrations and pictures, using written material on a low reading level. Information is given in small sequential segments so that the students are not overwhelmed with the amount of information to be learned. Short review sections titled "How Much Do You Remember?" aid students to learn individually the information that is grouped together before going on to the next segment. Material introduced in this manual includes the fuel system, the carburetor, the air cleaner, types of carburetors, safety, and good work habits. (KC)
