Default Re: Plug Picture...Lean or Rich?

you may be right, Dave. i was thinking with a newer engine and a rich oil mixture, it'd take a little longer than 15 minutes before it got all gunked up and turned black.

on a tuned engine, a coupla blasts up and down the street would probably be enough to see what's up.
