just pulled after changing my needle setting last night, so about 4 miles since then....yes carbonated, but not white or a light grey as shown on the "bad plug" pics. overall this plug has about 150 miles on it though, run at a much richer setting
So I will recheck it in 25 more miles or so, and see how its looking then, will prolly have the plug sandblasted to clean it throughly first though, so we can see from a fresh start
