Do lawn mower spark plugs come pre gapped?
Check the gap on the new spark plug before installing it. A new plug will often come pre-gapped to match your specific engine, but use a spark plug gauge to verify that it matches the manufacturer's specifications.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.Spark plugs are typically located on the back or side of a lawn mower engine. Look for a short wire that's about 1/4-in. -thick leading to the top of a short, cylindrical protrusion from the engine. If you're not sure where the spark plug is, consult your owner's manual.
