Read my plugs.

What are you trying to learn from reading your plug? If it’s wot fuel, you need to not idle around and drive on it. Just make a pass and click off the ignition, then look at the fuel ring (cut the plug to really see it or get a plug viewer). Timing? Looks a few degrees light to me. I’d guess for best power you’d need two more degrees in it. Heat range? I’d say one or two ranges to hot. No color in the base or threads. Idle and cruise fuel? You’re probably not far off and relatively lean. Might fatten it up a skosh.
