Too tight it sings, (Whines) not buzz.

Too loose, it slaps the inside of the TB cover and can sound like a buzz.
Make sure the TB cover is properly seated in the lower half.

The belt should be just tight enough to make it almost, but not quite,
impossible to slide back and forth on the pump sprocket, not more than 1/8"
each way, with 2 strong thumbs.
