Bad PCV? Idle issue

Not a bad idea at all.
That's strange that cutting the fuel didn't change anything if it was running so rich, so it may very well be the power valve.

Well it wasn't dripping into the carb and the float levels looked good.

The only other thing I can think of is to turn the idle air bleed screw all the way in. If it still idles the fuel must be coming from somewhere
