In order for this engine to start and run, it needs a specific type of spark plug that fits its design.

Briggs and Stratton’s engines typically use either Champion or NGK brand spark plugs. These plugs are available at most hardware stores and online retailers that sell lawn mower parts. When purchasing a replacement plug, be sure to get one that has the correct reach and thread size for your engine.
The reach is the distance from the tip of the electrode to where it meets the threaded portion of the plug body. This measurement is important because it ensures that the electrode makes good contact with the combustion chamber walls when installed in the engine.
The thread size tells you what size wrench or socket you’ll need to remove/install the plug. Most importantly, don’t forget to gap your new spark plug. Gapping simply means adjusting the distance between electrodes so that they create incorrect electrical charges during firing.
Improperly gapped plugs can result in poor performance or failure to start. Check your owner’s manual or service manual for proper gap specifications for your model engine.
