2001 sportsman 90. I took the carburetor apart yesterday. Cleaned it out completely. I found a few things I had not seen before and man were they dirty. So I put it back together slapped it in and went to adjusting. Now the odd thing is I had the mixture screw all the way in and that’s where it was running the best. Still lacked a little power up hill but ran at least 2 hours never having to push the atv to get it going. First time it has done that. The bad thing is it smokes more than it should and the snappy 2 stroke power isn’t there (yes I know it’s only a 90) so any ideas on what to do? I finally got a repair manual and was looking at the clips on the needle jet could this help?
