The first thing to check is the idle setting on the carbs. chances are they need to be turned down. Also check the rubber boots on the carbs for cracks.Replace them if they are cracked.

They're the "grippy" looking screws you can turn with your fingers, on the side of the carbs.

Your first problem is you POSTED THIS TWICE! Start with one... I bet you are impatient, that could be part of your problem...

Moving my idle screw does not really do much, how much do you have to move them, a lot? My sled is idling around 1200, I don’t think it’s really hurting it, is it, I would rather move it up a little. Any suggestions?

Does turning it out raise or lower the idle?

Depends on which way you turn it. You may have some dirty carbs though, and you should consider cleaning them.
