time to start fine tuning !?

The car seems to be pretty solid now But, I'm wanting to get some more fine tuning actually. My timing down to all in at about 36 to 38. Oddly enough it seems to run and idle faster at even higher timing? I do have a wide bands o2 sensor and its reading about 12.8 to 13 at idle and it goes down to like 11.2 -10.9 that wide open throttle? I'll ad some pictures of my spark plug and the size I'm using? all experience would be greatly appreciated, thank you . ...Attachment 1714830311
