this is happening because your pilot jet is too lean. This is very common on all newer flatside carbs, happpens on our two 04 Summits 800's, my 03 Cat 900, my buddy's 08 Summit 800 at lower elevations... Since these sleds are setup for the mountain, they won't do this up in the hills.

I wouldn't worry about it too much.... At least were not. Just blip your choke, and it should stop the high idle, then shut off the sled.
