Other than that P.T. Barnum spark plug having three too many ground electrodes, I don't see a problem. If you're running no-lead gasoline, spark plug color is not an indicator of fuel mixture. The "tan to chocolate brown" color we looked for 50-something years ago became impossible to find once the lead additives got removed. Now plugs will have one of two colors- - - -white or sooty black once the mixture gets WAY too rich. A really lean mixture will cause a shiny, blistery appearance of the porcelain plug tip, and a severely eroded ground electrode. Extremely lean mixtures will also detonate, burn holes in pistons, and burn exhaust valves.

What's a "flipped piston"????????
