My 1995 Polairs 440 fan Indy Sport sled has had an issue with the carbs. Each carb has an outlet about mid way up the throttle body that was never connected to any hose or anything. In the past few years typically in the fall when I would first fire up the sled fuel might come out of either outlet when the sled was running. Typically after driving it a few hundred feet it would stop and I would be good for the season. This fall I could not get one of the carbs to stop spewing fuel out this outlet so I took the carbs apart and cleaned them. Floats did not have any fuel in them (sometimes they leak and sink thus calling for fuel when they don't need it) so I just put it all back together. I have put about 100 miles on the sled since that time. Now both carbs are spewing fuel out those outlets again and won't stop. If you gas it they will stop but at idle or slower speeds that don't call for much fuel the gas is just coming out. Ny ideas?
