spark plug recommendation

[tubman]

Back in my snowmobiling days, reading plugs was very important. We wanted to go as fast as possible, and that meant "leanin' 'em down" as far as it was safe to go. Of course, if you went too far, you ended up with a hole in a piston, which wasn't good. In those days, we said that if you bought a Hershey Bar and broke a piece off, the color of the broken part was what you wanted your plugs to look like.

These days, gas isn't what it used to be, and Hershey Bars probably aren't either.
