I went for a ride today and all was well until i opened the sled up to full throttle and the sled died. And would not restart for a hour or so than pulled the plugs cleaned them and sprayed some carb clean on plugs and the sled started and idled and ran fine. Until I opened it up again and sled died right away. When I pull the plugs they look completely dry so I dont know if it is a fuel issue or what. Any help would be appreciated.
