Well, it started when i was going to ride last sunday after the snow storm. The choke was frozen out so that it was past full choke. I used a blowdryer and it went back in and it rode fine. Today i went to ride and the choke was frozen out and i did the blowdryer thing but when i rode it it was smoking badly and running really rough so i stopped. Bringing it in tomarrow, any ideas other than the choke? It seemed to be all the way in when i started it up, but ran awful.
