Spark plug readers

Don't if it's the lighting in the photo, but the strap looks a bit white to me. That would be an indication that you are running a bit lean (or have a little bit of a hotter range plug), but I don't think by much. I don't know why everyone commenting can't straight up tell you that. The color you want to see is some very light golding or browning on the strap almost like the one I have in the photo.
