Have you checked fuel pressure and the pick up filter ? That sounds like a lean sputter (I call it). If you were having cavitation issues from a worn impeller or wear ring, they would be showing up at a hard hole shot also. I'm assuming that if you even back it off just slightly it clears up, or does it need to be closer to 3/4 for it to clear up ?
