Well float levels are good the PV # is good enough to be closed. either the idle circuit is WAY off which I doubt if it could be causing this much richness or the PV is blown (common) or the gasket behind it has lost a piece (less common) or WAG could a piece of the carb be loose but my money is on the PV that it's blown. do holler when you discover what it is
