Background and Information

Most lawn mowers are powered by a small gasoline engine. Of these engines, many are one-cylinder four-stroke engines. While the specific parts of these engines may be unique to their model, the general layout and function of engine components is mostly the same across the board. All four-stroke lawn mower engines have an air filter, a carburetor, a cylinder head, a governor, and so on. Since these work on the same principles regardless of the manufacturer, guides about the repair and replacement about this part may be generalized.

Due to the harsh mechanical climate of a running engine, components are subjected to grueling conditions such as high heat, pressure, and immense forces. While the parts are designed to take these punishments, over time they may begin to wear and tear to the point that they no longer work. Luckily, engines are fairly simple to disassemble.

The engine used for this guide is a Briggs & Stratton 300e series push mower engine. This engine in particular was released in 2014, with other 300 series stretching back to the early 2000's. To help identify this mower, the manufacturer printed the model number in one of three places. It can be stamped above the spark plug, on the front of the engine, or above the muffler.
