Spark plug gap

they sell gapping tools at most auto part stores they are only about 1 dollar.

Do not pry on the center electrode when gapping, you could crack it and cause a miss in that cylinder.

Do not gap. Buy pregapped spark plugs. I believe they are set for .40.

It is always wise to at least check the gap on a spark plug pregapped or not. You never know unless you check that they are at the right gap or not.
