How to Remove a Spark Plug From a Lawnmower
- 1). Stop the engine and allow it to cool off completely.
- 2). Remove the black rubber boot from the spark plug and move the plug lead to one side.
- 3). Place a special plug socket over the spark plug. Push the socket all the way in to fit it over the hex nut on the spark plug. Crank the handle counterclockwise and remove the spark plug from the engine.
