Sounds like it's coming from the dizzy. I don't think it's the generator or water pump. This is at idle:

Anybody got ideas?

Re: New Noise
How about the clutch area? Try depressing the clutch pedal slightly while running to see if that makes a difference.

Re: New Noise
There was a lot of competing or background noise in the video. Is it possible to separate out or filter the sound?
Could be a worn camshaft, oil pump issue, valve lifter, distributor, generator or water pump bearing, etc, but go simple first.
What about the belts? Are they in good shape?

Re: New Noise
Pull the belt and see if it goes away. Quick and eliminates a bunch of items.
Re: New Noise
Excellent suggestion!
To me it almost sounds like high pressure air leak. Time for a quick compression test

Re: New Noise
Go get one of those cheap auto stethoscopes and simply touch each component. When you hit the right one you will know it!

Excellent suggestion, Murf.

Re: New Noise
Same noise with the belt off, and after torquing the manifold (several nuts were loose).
