i have a 2004 sportsman 90, the machine will start with full choke in the cold weather. if i touch the choke or feed it any throttle it will stall instantly, i wait 10 minutes to warm up and then it is still not guaranteed to rev..... i had the carb cleaned and tuned last year and the machine ran great up until the cold weather.... does any one have any tips

thankls in advance

Will it run with the choke on or at least half way on.

 

The 2007 model is the same. Get the correct oil in the machine. Ours takes about 10-15 of driving to warm up.

 

His machine is a 2 stroke no oil in the engine. I hate to tell you but the carb is most likely dirty again. You need to keep fuel stablizer in these things all the time. I add it to the gas can before I go to the gas station so its always in there. Gas these days is crap.
