These engines are used in motorboats, motorcycles, chain saws, lawn mowers, and other equipment. Small engine repairers work on engines used in motorcycles, motorboats, yachts, chain saws, and lawn mowers. Small engines need regular servicing to keep down the possibility of breakdowns and keep them operating at their best. Mechanics do cleaning, adjusting, and lubricating. When necessary, they replace worn or defective parts such as spark plugs, ignition points, valves, and carburetors.
Routine maintenance is normally a major part of the mechanic's work.
When there is a breakdown, mechanics get a description of the problem from the customer. They then find the cause of the problem and install new parts or make adjustments. Repair work may include tuning ignition systems, overhauling carburetors, replacing piston rings, honing cylinders, and installing new bearings. They use service manuals to find detailed specifications. A skilled mechanic has the ability to diagnose fuel, electrical, and mechanical problems and to make repairs in the least amount of time.
