My 96 Polaris 600 XLT is leaking fuel into my carbs when it sets any lenght of time. Is this normal for this model? I did install a new fuel shut off. The old one was broke. I can't believe $23.95 for the Polaris fuel shut off. Briggs & Stratton $6.95. I did take the carbs off and clean them and check the float levels they were right on. Needle and seats are likly the problem. I was wondering if anyone else has the same problem?
