I have a 2001 polaris xc sp 600, and on New Years day I was out riding in my yard, and i knew i was low on gas but I wanted to use it all because the previous owner gave it to me with a half of a tank of gas. I was going like 50 MPH accross my back yard, and it shut down. I looked in the gas tank and it was bone dry. We didnt want to go down to get gas so it stayed in my yard from that day, till yesterday. We put gas in it and now will not move. When I start it, it idols and i can SLOWLY push the throttle untill 2500 RPM's, and it shuts down. But if you let off it goes back to idol. :wtf: is wrong?
