What happens if you put the wrong spark plug in your lawn mower?
Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.Here's How to Know if a Lawn Mower Spark Plug is Bad
