So looking through my notes – Laguna air is often between 500′ and 1000′ relative air density. And we have run 182, 180 and 178 – 182 for around 500 and 178 at 1000 and higher. Again – I am always checking plug color and EGT behavior and adjusting around that. Laguna is also not very much on long straightaways. For same air, at places like Thunderhill and Sonoma, I stay on the richer side as the long WFO sections need the fuel.
I don’t have access to the kart to verify the pilot, but I believe we have a 60 in there and the needle I don’t remember either – but there is pretty much just one needle all the road racers use. This is all on a PWM, without airbox.
