I can find nothing wrong in any of the pictures. That picture of your bowl also looks fine (because there's no gas in the float bowl to make it rise). To reassure you, here's a picture of mine, which is properly calibrated, although you can not tell it from the picture.



The only way I know to test a Power Valve is with a vacuum pump and something like the Moroso tester. But you can push the plunger back and forth with your thumb and finger and try and feel something different from the old one. I think I would just put the old one back in for now -- we're pretty confident it was working alright and if the new one is "stuck" in the open position, that could contribute to an overly rich mixture. An open Power Valve generally boosts up the circuit by a good ten jet sizes, which is quite a lot.
