Could you possibly be able to record this ? and upload it to Google Drive , then get a public share link , post the link here to view it.
But do check the clutch basket , rattling is something spinning, so I hope it is just a thrust bearing for the clutch or 1 clutch plate that has worn down too far and it has cracked (Happens actually) then its just clutch overhaul job.
Tensioners Cam = I am not sure what to say just yet until you get it running fully or check the flywheel area to see if the sprag clutch is making noise there ? or a rattling worn out starter motor ?
Just have to find the source of the noise as far as you can.
