Default carb leaking primary's

Ok all you brainiac carb guy's out there, I need some help. Carburator is a holley 750 double pumper 4150.
when at idle the carb is leaking out of one of the venturi's. now I have seen carbs do both but never one only.
Float level is fine.
not sure on gaskets but what could cause it on the gasket?
power valve has been changed, rechanged, etc.
anybody got any ideas? carb is pretty much new.
my idea, maybe that butterfly is slightly bent or open.
not sure.
Thanks
Al
