eton bemer matrix 2 have to choke

[scooterduder]

whats up dogs im scooterduder this is my first scooter dont really know much about them so i have a question. my scooter starts up fine it will idle fine but when i take it off choke it stalls when i give it gas. It will run fine on 1/4 choke and when i go down the road i can turn off the choke and its fine, but when i stop and give it gas it stalls. i was told its lean or getting air so i have to choke it. my uncle sold it to me for 1000$ it has 2000 miles on it. it was stored for a year with 1/4 tank and some stable in it.could this be because of the gas or just cold weather related? i put about 100 miles on it and it still runs like that. if you guys could help that would be awesome thanks. s.d.
