I will be working on the illustrations at some point and will try to improve clarity.
How many DPI shall I save them at? How many pixels you all want?

p.s. no Steve Kent, no. A lean mixture that is real lean does NOT extend the burn into the exhaust causing Armageddon, because the whole point of this exercise (that shows up on the CHT gauge, hello)
is that we are starving the burn. There is no further combustion left by the time the exhaust is going out the port. My late model bus exhaust system with the headless bolt flange on the left manifold is now at 133,000 miles since new, 70,000 miles past when I dremelled all the bolt heads off, it is terrible to look at, but not a wisp of soot leaking from the gasket. Let's chill on the catastrophisizing shall we?)

Nothing wrong with running 15-16 afr at cruise. It is actually cooler than 14.7 at cruise. The added heat comes into play with throttle position (excess) not part throttle condition/s.
