Spark Plugs

For standard lawn mower and small engine maintenance, you should check and/or replace spark plugs:

  • Annually and in accordance with the Operator's Manual
  • If your lawn mower or outdoor power equipment won’t start

The electrodes on a spark plug must be clean and sharp to produce the powerful spark required for ignition. The more worn or dirty spark plugs are, the greater the tug on the rewind and more effort is required to produce an adequate spark.

If you haven't tuned on your engine recently, your mower won't start and/or you have to tug repeatedly on the rewind to start the engine, a damaged spark plug may be the culprit. These problems may also cause excessive fuel consumption, deposits on the cylinder head and oil dilution.

Luckily, spark plugs are one of the easiest and most inexpensive engine components to replace.
