Hello,

 

35 degrees BTDC all the time verified via timing light. Info from = Tracy=E2=80=99s manual and tested by me for most power in flight. 100 LL = gas with 2 cycle oil @ 1 oz. per gallon. 6,300 RPM stock = 13b.

 

Thanks,

Dave Williams

Dave =3D 35 all time? Doesn't = that seem really high for rotary. Pump gas? Lynn was saying 24 degrees = for 87 octane.
