Small gas engines serve us in many ways. They power lawn mowers, tillers, cultivators, trimmers, edgers, snow blowers, chain saws, pumps, generators, air compressors, and other useful home tools.

They also power our fun: outboard boats, snowmobiles, motorcycles, all-terrain vehicles, ultra light aircraft, and other toys. To keep them operating efficiently, an owner of these tools and toys should know about small engines: how they work and what to do when they don?t.

Small-Engine Fuel System
The function of a small engine fuel system is to store and deliver fuel to the combustion chamber. Maintaining a fuel system includes servicing the fuel filter, air cleaner, fuel tank, and fuel lines; adjusting the carburetor; and adjusting the governor. Of course, not all small engines have all of these components.

Small-Engine Ignition System
An ignition system in a small engine produces and delivers the high-voltage spark that ignites the fuel-air mixture to cause the combustion. Some small engines require a battery to supply electrical power and the ignition spark. Others develop the ignition spark using a magneto.

A small engine ignition includes the ignition controller (mechanical-breaker, capacitor-discharge, or transistor-controlled), spark plugs, flywheel, and wiring. Servicing the ignition system of your small engine depends on which types of components it has. Below are step-by-step instructions for servicing ignition systems found in modern small engines.

?Small-Engine Lubrication System

Friction causes wear; it?s a law of physics. Small gas engines can wear out prematurely if moving parts aren?t lubricated. We?ll discuss how to reduce wear on your small engine and increase its useful life by servicing the lubrication system. Topics include the fuel-oil mixture for two-stroke engines and performing other lubrication services.

Always use the type and viscosity grade of oil recommended by the engine manufacturer. Lubricating oils and additives designed for four-stroke engines are not suitable for two-stroke engines.

Small-Engine Cooling, Exhaust, and Control Systems
An internal combustion engine can develop an internal temperature as high as 4500 degrees Fahrenheit (2200 degrees Celsius) during the power stroke. Obviously, a small engine?s cooling system is critical to smooth operation as well as long engine life.

A defective cooling system can ruin an otherwise good engine in minutes. Fortunately, small engines have simple cooling systems that require little maintenance to operate for many years. A small two-stroke engine is typically air-cooled.
