Power Mechanics includes hands-on lab work, reading assignments, and written classroom exercises. In this small engines class you will learn principles of engine operation and construction, the differences between 2 and 4-stroke engines, carburetion, complete disassembly and reassembly of small gasoline engines, and mechanical components of an engine. Reading from technical manuals (repair and service manuals) is an essential part of this course as is the ability to measure and perform mathematical calculations related to small engine mechanics.
