I used Sidewinder race 30% and odonnel 20% all with 12% oil
maybe I ran it too lean because I was always pre heating it but I would run out of fuel at the final lap of a 5 minute qualifier.
So some guys at the track helped me adjust it and we ended with 4.25 turns on the LSN and 3.1 turns on the HSN
