I have had this happen before. The sled was also a 97v max. The problem was a small crack in a angle piece coming off the tank.With that crack it pulls in air and cant create suction. We found it by blowing air in the tank . So maybe thats your problem or most likely you have to clean your carbs.
Try putting some starting fluid into the airbox and give it a couple of pulls, that should get it started and once it is you may be able to better diagnose the problem, and if it doesn't start, get out some carb choke cleaner and spray it into the carb.
