I don't believe many of those charts anymore. Unless there is something obvious, like oil or soot on the plug. The color coding as a means of tuning does not work that well with the newer plugs, the materials they are made from, and the gas that's available.

For me to get my carburated Harley to begin to get close to that tan color people try for my mpg goes to about 10.
