Metering Plates, six pack

It's been 2 or 3 years, since I started this thread. I have a little better handle on this. Think the reason that my plugs always look bad is non ethanol gas, but haven't driven the car this year yet because of other updates to car. My other cars plugs are clean with ethanol gas. Thank you Woodys_cuda for the tip. Will keep for the future!
Thank you
