Good post for sure! My plug colour has been kinda making me paranoid because they are a medium grey kinda inbetween pic #19 & 20 and I felt maybe it was running lean, but even the Clymer manual says light tan to grey is acceptable. I have never seen a grey plug before, all of my 2 strokes run light to dark tan which I was told to understand as ideal. At least I can breathe a bit easy now knowing grey is ok.
