Hello, i havent touched my 600f4 in prob 5 years or some +

I am goin to sell it, but i am having problems with the fuel supply.
When i am trying to start the bike, it is rough started, and its spitting out fuel. ( i reccon its from the carb)
It does start, but i have to have the "choke" and give it abit of throttle, but not to much... then it stalls

please take a look at the video
