Kitty Cat Snowmobiles

I went out to the garage the day after the kids were riding our 95 kitty and it drained its gas tank and it appeared to be coming out of the exhaust pipe underneath. I assume the float must have stuck open? Any ideas? Anyway i pulled the carb off to go over it and figured I would change the gaskets around the carb and the silencer as it appears that someone uses some sort of silicone gasket caulking to seal up. I also pulled the exhaust to drain any gas out of it and the exhaust gasket needs replaced. Can anyone direct me where to go fo rthese parts?

you should be able to get them at any A/C Dealer, they may have to order them, but being that it is the Suzuki motor, parts are still readily available.
FYI, I always made it a habit of shutting off the fuel petcock when it wasn't being ridden, I have seen the puddle of gas on the garage floor myself.
