How can I tell if my lawn mower’s spark plug is faulty?

To determine if your lawn mower’s spark plug is faulty, start by removing the spark plug using a spark plug wrench. Inspect it for signs of wear, such as cracks, carbon buildup, or corrosion. A clean plug should have a light tan color. If it appears black or oily, it may indicate flooding or oil leakage in the engine. You can also use a multimeter to check for continuity. If there’s no continuity, the spark plug is likely defective and should be replaced. If the plug looks good but the mower still won’t start, the issue may lie elsewhere in the ignition system.

Can I test the spark plug while it is still attached to the lawn mower?

Yes, you can test the spark plug while it is still attached to the lawn mower, but it is recommended to remove it for a thorough inspection. To test it while attached, use a spark plug tester. Disconnect the ignition wire, then connect the tester to the spark plug and the ignition wire. Crank the engine; if the tester shows a spark, the plug is functioning. However, this method won’t allow you to inspect the plug for physical damage or wear, which is crucial for ensuring optimal performance. For the best results, removing the spark plug is advisable for a complete assessment.
