I am by no means an expert banana, but (IMO) I believe alleyoop was correct about the belt not riding fully in the bottom of the variator pulley!
Maybe one or more of the rollers/sliders (or u shaped slides) has become dislodged and now the variator is stuck (open), a little bit. This will make the scooter take off real slow and most likely buck or want to die when stopped. Kind of like trying to take off in second gear with a manual transmission.
Yesterday I rode my scooter 16 miles on the interstate, and when I came to a stop, my scooter was bucking and wanting to die/quit. When I went to take off the scooter would go real slow, until about 10 miles an hour, then it ran fine as long as my speed stayed above 10-15 miles an hour. When I took my CVT cover off and looked at what was going on, it looked a lot like your video. The variator is jammed open, about 1/2 in., and the rollers/sliders (or U shaped slides) will not allow the variator to close. A closed variator would allow the belt to ride in the smallest area of the pulley but since the belt is riding higher in the front pulley it will ride lower in the clutch pulley making the clutch engage while sitting still. Centrifugal clutch! This is really bad for the belt!!
I am guessing about the cause of the stuck variator! I, also, can't remove my variator nut to verify the cause of the problem! I put a small amount of blue loctite on the nut, when I had it off a few months ago, and now even with a compressor and an impact driver I can't remove the nut! Story of my life, (insert...long sigh here!).
Good luck with your scooter! (Wow, that's a lot of snow! Pretty but..... yuck!)
