I Run 110 Turbo Blue Fuel, and will be using a 42 Pilot, and 190Keihin main. My question Is the # of turns for air fuel and which clip to set the needle at?

I was thinking 3 on the clip and 2 turns and A/F?

3 and probably 2.5 would be better than 2 but you can tune it accordingly pretty
easy.

that will get you started, you can just listen to it to get it pretty close though, you dont really need a tach to do it.
