Spark Plug = Lean / Rich
So I did my heads and cams and I’ve had them on for like a month and didn’t get a tune yet, so I take off a spark plug to see if I can tell if the car is running too lean/rich and I find out that the tip of the plug is like dark gray and slightly dark around the treading, does this mean I’m too lean or Im ok
