Turn the pressure down a little on that hose. I'd check exhaust cover gasket then all fuel line connections.

Towards the end of the video it sounded like it was running on 1 cyl. Pull 1 plug wire at a time when running and see what happens.

Have you tried adjusting the low speed adjustment? I had the same issue and that fixed it. I have 2 videos one is before and one is after. Watch them and see if that is what you think yours sounds like. If it is simply run the low speed idle adjustment screw all the way in and seat gently, then mark with a sharpie and back out 3 full turns.
