I saw 12-12.5afr on cruise 1/8-1/4 and 13.5 1/2 cruise on flat road. My idle is now at 13.3-13.6. What are you thinking?

Is there an inl-ine or inductive spark tester that will test for weak spark on a running engine?. Like yellow if its weak and blue if its good. The $6.00 tester I have just shows a yellow light on any engine I test.

I don't think it's a coincidence that the sooty plugs in your first pic (2&3) are fired by the same coil and pick up ?????

colour in the second pic isn’t too bad, don’t forget the coil is only as good as the pick-up and igniter that trigger it
