I would like to add if anyone ever visits here and gets this far...
Lean burn only works in low rpm conditions. if WOT than this is "lugging" in the extreme

the timing must be advanced and the rpms must be low because the flame front is mush slower
but if you are able to "complete" the combustion before the exhaust valve opens you will prevent valve damage and make useful work of energy.
