No, it didn't. Perhaps there wasn't enough water to roughen the engine...a little ice well-placed, maybe? That's actually one reason why I asked my IA about it...only the lasting improvement given by carb heat pointed to carb ice. I had some doubts that perhaps carb heat was masking the real problem, by richening the mixture and/or activating the alternative air source...which would help in the case of, for example, a badly bugged up air filter. However, having steady, full, static RPM on the ground suggests that whatever it was is something...like ice...which got gone. Remember, this wasn't the classic situation where RPMs began to fade away with restriction of the venturi. Something more interesting clearly happened inside that carb.
