Not Ranked
What model Quick fuel carb do you have here?
What size IFRs?
A lower number PV opens later, not earlier. Your 6.5 is fine while the engine idles at 9.
The engine idles at 9 because of your cam profile, but vacuum increases with rpm increase at light throttle. Completely normal for larger than stock profiles.
