Easiest thing to check would be for an intake leak somewhere. I would say sticky valve but, if compression is coming back good that's probably not it. Slide carbs? Diaphram carbs?

Just went back and looked at your video. Those carbs look like diaphragm carbs, they have slides in them but they have a big rubber diaphragm that gets sandwiched between the cap of the carbs and the body. I would pull the top off that carb and see if your rubber diaphragm is ripped or has a hole in it. Also I know it simple but is you throttle cable or the butterfly on the carb stuck open in any way?

Responded to youtube. Wonder if someone rephased your crank to reduce vibration

One cylinder is not firing. Check spark check fuel check air. When (if) those check out check ignition again. Lube your advance rod weights. Change your spark plugs and check the gap too
