Help !! Running super rich.

A blown PV does not cause boosters to drip. A popular misconception.

Boosters will drip [ at idle ] for two reasons: carb is flooding &/or t/blades open too far at idle.

"Blown?" If you mean "blown" as in the diaphragm is ruptured or the gasket is torn, the thing leaks fuel directly out of the fuel bowl and right into the intake.

But you won't (likely!!) find THREE blown power valves in three different carbs!!!
