Definitely the carbs will have to be checked and most likely rebuilt. Don't buy the aftermarket kits, only Mikuni. Also check the crankshaft seals. The 2 cylinder ones aren't that bad but the 3 cylinder engines are known for kicking them out. Just got finished with replacing the seals on the 1100. Rebuilt the the carbs. For 20 year old skis, they run great.
