Try turning your air screws in to 1 turn out and see if it gets any better. Also, adjust your idle when it's warm.

going out to try it right now do you know what the needle clip is supposed to be set at? cant find it any where the polaris dealers around her are more interested in selling 4 wheelers and side by sides and dont really even handle sleds anymore or want to work on them

If they are adjustable, should be 2nd clip position, May not be though. I think they went to adjustable needles in 2001 on some models. They had a lean spot in the midrange just like some other sleds. IF the sled just started acting up without any settings being changed you may want to make sure the pilot circuit is really clean (jets and passages) and get the air screw to 1 turn out. Polaris's I've worked on it was an air screw (airbox side of the carb slide).

Never seen that before. Is any of the tip visible in the carb bore? I would squirt some penetrating oil down in there hopefully loosen any corrosion. maybe you can a screwdriver tip in there and catch just enough to turn it out. They're only brass so pretty soft. If not maybe a very small drillbit and then an easy out. Just take your time.
