Spark Plug Cleaning
I'm playing around with my jetting and reading my spark plugs as a guide as to how rich or lean I am running. My first read of the plugs was that I was running very rich (entire plug was black). I made some jetting adjustments and went to read the plug again and got the same result.
My question is this...If a plug shows a rich condition (all black) and I lean it out will the plug turn back to a normal color or once it is black it never goes back (please, no pun intended here).
