stratus
8:18 ratio, YS 91 SR Engine, SB19 Pipe
I'm running:
12.500 rpm in idle up 1 = 1528
15.500 rpm in idle up 2 = 1894

High needle = 0.9 open
Mid needle = 1,75 open
Idle needle = 1,0 open
Fuel = Wildcat 30% LV
Glow Enya 3 or 4

I use a CSM Carb Smart, temp set at 100 degrees
The Needle setting are when the Carb.Smart is at max lean position.
The Carb. Smart is adjusten both needle, and can turn then 90 them both degress.
