Spark Plug?
(Click here to view the original thread with full colors/images)

Hello,
I have switched to 100 low lead w/amsoil 50:1 and my R is finally starting to run good and the plug is okay in color (dark brown/black) but sometimes it is brown and black on one side of the tip or brown/almost white?
Does it mean anything on the ceramic below the tip of the plug as to what color it is there?

Thanks
Bubba
