That would be great - thanks.

Last weekend, I took a 200 mile trip for the day with AFR's primarily in the high 13's and the plugs were light tan with the grounding strap nearly clean. I considered this too lean. I richened the AFR's to show generally low 13's (in normal around town driving) and now have a dark or mocha color (the metal case of the plug is black now). My idle is 1.80ms using Siemens Mototron 60lb injectors which gives me 13.8AFR.

I'll take some pics to show what they look like now.

I would also be interested to know what you think the gap should be on a wasted spark system, spark plug.
