I don't have any pics. On alky, a plug looks like new if it's too rich. If it's too lean/hot it turns black or dark brown. The base of the threaded part of the plug will begin to bronze starting at the strap, as it gets hot. Where it is not burned, it is still shiny, like new. Ideally you want the marks on the plug to go to 9 o'clock and 3 o'clock, with the strap at the 12 o'clock position. My plugs show that it's rich, so that's why I'm stumped about it not smoking. I can kind of see why the pipes would be hot if it's rich...the flame is burning farther into the pipes, right?
