Instead of waiting for signs of wear and tear, I wholeheartedly recommend following the manufacturer’s guidelines from the get-go.

• Tools Needed

The tools required for changing a spark plug are fairly standard and most likely can be found in any typical household garage. You will need a socket or wrench, a spark plug socket, and a spark plug gap gauge.

The spark plug socket is specially designed to hold the spark plug during installation and removal safely. The spark plug gap gauge, on the other hand, is a tool that measures the gap between the center and side electrodes of the spark plug.

• Steps in Spark Plug Replacement

Replacing a spark plug is straightforward if you know the drill. First, locate the spark plug on your mower. It should be fairly easy to spot; it’s usually on the front or side of the mower and connected to a black wire.

Once you’ve located the spark plug, disconnect the spark plug lead. Make sure you pull by the boot, not the lead. Before removing the spark plug, clear any debris from around the base to prevent it from falling into the engine.

Next, use a spark plug socket to unscrew and remove the old spark plug. Replace with the new plug, making sure it is screwed in firmly but not overly tightened, which could damage the threads.

It is essential to confirm the spark plug gap using a gauge before re-installing. The gap should match the manufacturer’s recommended setting. Once confirmed, re-install the lead to the spark plug. Make sure it “clicks” or snaps into place to ensure a proper connection.
