Small engine repair involves the maintenance and repair of small engines typically found in equipment like lawn mowers, chainsaws, and generators. These engines are usually gasoline-powered and have fewer components than larger engines, making them simpler to work on. Common tasks include changing spark plugs, cleaning air filters, and replacing fuel lines. Technicians in small engine repair often diagnose issues by inspecting the engine and testing its components. They may use tools such as wrenches, screwdrivers, and diagnostic equipment. Proper repair can extend the life of equipment and ensure it operates efficiently, saving users time and money in the long run.
