This will be my first year plowing with the 500 carb ho. How is the stock jetting in the cold temps? Is their any changes you have to make for cold weather? I am coming from 2 stroke snowmobiles and it you ran it in different weather the jetting was effected.

Thanks

iv always left it. i had a 2000 and now i have a 2008 500 sportsman carb. and i havent touched the carb. i plowed with it last yr with no issues.

 

I run our 97 sp500 and my 01 500 HO in the winter on real cold days and the machine behaves the same as in the summer. I wouldn't mess with anything. just let it idle for 5 minutes before you ride. The bottom pic was like 25 below but the ATV started and ran as good as the 2 stroke sleds did.
