Spark Plug Torque Specs

When I was young my Dad worked on Johnson / Evinrude outboards, and a few other orphans in our small town. The NAPA store had the Johnson consignment. (He used to cuss some of them, seems like Atwater-Kent was one, or maybe it was Scott-Atwater)

I learned EARLY that you don't overtighten plugs. Many, MANY outboards, lawnmowers, and other small engines have SHORT reach ALUMINUM heads. It is REAL easy to strip those.
