Hi Guys

Can anyone comment on mixture settings where you would expect a Renesis engine to begin to miss.
I take it this is dependant on plugs and coils.

We are using D585 coils with BR10EIX plugs gapped at 0.02
During Takeoff WOT I’m getting missing at rpm of 7-7.5K if mixture goes richer than about 0.85 or 12.5 AFR

Any thoughts?
