Default Re: Spark plug failure question

I have very rarely found a spark plug properly gaped right out of the box.
The factories just assemble them and leave gap adjustment to the installer. Not all engines have the same requirements so the gap needs to be set to the particular engine's requirements.
Set your plug gap to .024 - .028".
