Holley/Demon Carb stumble

The Demon catalog shows the IFR for a downleg booster 850 Mighty Demon is supposed to be .038”.

Emulsion holes- bottom .033”, other two 031”.
Siphon break .028”
PVCR .059”
IAB .070
HSAB .031
Stock jetting 85/93

I don’t feel it’s likely the best carb for CF’s combo, but the one I had and was using for a dyno mule....... I only did a tweak to the air bleeds and jets.
It was actually one of the better running Demon carbs I’d used.

However, I was using it for higher HP builds mostly.
