Ka-pow!

Thanks AJ, I may just have that problem though. I wish you would have posted this info before I put everything back together.
The thing is sure running pig rich for some reason I can`t see how the power valve ruptured, but I guess anythings possible, I just pushed a little on it`s plunger to check it`s operation and it sprung back good but did`nt pull out to inspect closer because I did`nt have a spare gasket. This thing went from running plugs that looked like they never been fired to sooty wet, and near eye watering rich. Something happened...
I guess I should pull the damn thing again and inspect the power valve for ruptured diaphragm. If rupture can`t be seen, maybe just replace it and hope for the best.
Thanks for the input
I would think that if your power valve was ruptured you wouldn't have much acceleration (especially "off idle" in gear). When you have a bad PV or the wrong PV you get a distinct stumble when you try and accelerate. But it doesn't hurt to check??
