These plugs were actually new a couple hundred miles ago. I know I didn't stick in a new set of plugs and do a wide open run, but I did a full throttle blast and then idled for about 1/2 mile after that back to my house. The plugs have like no color or anything on the ground strap. Are these plugs really lean or about right? BTW, they are Champion RV17YC6 spark plugs with a cut back ground strap.
