I have 3 plugs that I have chopped, and would like to know which one appears to have the best tune. The one on the right is out of my dads Ltz 400 the 2 on the left are out of my kfx. I am trying to get better at reading these things, so hopefully I'll get some good feedback on this.

The far left looks to be close to optimal...The middle & far right are carbon fouling..What color exhaust smoke when you first start of the motor....?

Need electrode to see the heat on the ground strap...example see pics

I agree I thought the one on the left appears to have the best tune. I have the top sections as well but they all look very similar. I can't even see a point on the ground strap where there is a color change. I can post pics of those after work.
