I nothice a patch of "untouch" part on the plugs. Is taht something to be concearned bout?? (its real noticeable on plug # 3, they are all llike taht but the pic only shows the third plug)

Bad background Color. Next time use white.
I'd advise taking a close picture of each plug.

But from the looks of then, from what I can tell. You're running very rich.

 

Yup. Rich.

 

AGREED
running rich, the insulator is your best reference. if its black and charry its running rich. should be white. if grey and speckled may be a sign of detonation.

 

Dude, bukoo richness. Those babies are on the edge of fouling out.

insulator should be off-white and "dusty" not black.
