Sounds like your carb. Is bad they have new and used carbs on eBay..
Or a rebuild kit.. Same problem here on my Suzuki four wheeler I ordered a new carb. For 35.00 my husband slapped it on works perfect.

2010 sportsman 500 hd runs then dies turns over won't start


My opinion, it's running rich and letting it idle for 5 minutes doesn't help. Whether it's carbed or EFI, when the machine is cold, it needs more fuel. As engine temperature increases, it doesn't need as much fuel, and the carbon that started building up on the plug is burned back off. When a machine isn't ran for very long, carbon deposits continue to build on the plug. The carb itself may need to be rejetted/adjusted, it it's running rich,

I have a 2004 polaris sportsman 500 when it gets hot it cuts off and back fires


Does the cooling fan ever run when the engine is hot? If not, you may have a problem with the fan thermostat.

For the record, spray carburetor cleaner does no good if it's sprayed on the outside of the carburetor with the engine running. That's not what it's for.
