Started up the RB20 and noticed this noise, any ideas on what it would be?

Hard to tell, but kind of sounds like it could be rod knock.. It also sounds like you might have a cylinder or two not making compression.. Id check the oil for glitter, try this rod knock test https://youtu.be/pYleKxjl0uY and if that all checks out, do a compression test.. If its not any of that, then youre lucky because that sounds awful.

Does the noise go away if you push the clutch in?

Sounds like a bad throwout bearing, or some kind of clutch problem.
