Re: Is it timing, carburetor or something else?
A couple of things to check. Has the Harmonic Balancer slipped? It not uncommon for the outer ring to move in relation to the inner hub. Find TDC of #1 piston and verify that the mark on the balancer lines up with the pointer correctly.
From the video you posted you have some definite valve train noise. I would adjust the valves. Actually first since it is a I-6 you can remove the side covers and inspect the camshaft for bad lobes and if everything looks good then go ahead and adjust the valves
