Holley/Demon Carb stumble
Those blocks look like the've lowered the air well. I've seen that but havent dealt with them myself.
Compare that with the ones this guy bought
Need Quick Fuel carb tuning assistance
or this 3310-2
Fuel level is roughly at the same hight as the upper emulsion bleed (e-hole).
Lowere-hole is above PVCRs.
That's why plugging the bottom e-hole on those deep well blocks may be a starting point.
