So I've readjusted both belts and no matter what I do, that whistle is in there. I was able to adjust the balance belt to within specs on the Arnnworx tool, and it does feel looser than what I had before, but not so loose that it was flapping all over the place. I'm puzzled, to be sure, but I'll probably end up getting a stethoscope to really figure out where the sound is coming from. No whistle at idle, just when I rev the engine.

As a curiosity, I wonder how much the cold weather has to do with this and how the noise may change if I were to drive around a couple miles.
