Spark plug gap
What do I need to gap the spark plugs ?
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.
