96 Scrambler gas is coming out of the tank vent. First thought it was because I had the tank totally full but now even at half full it still comes out enough to get on me while riding. Somehow the tank seems to be under pressure. Any ideas. Thanks

 

I had that problem once. When I had the rebuilt done the mechanic also changed the check valve, ( I believe that's what he called it) in the carb. Never had that problem again.
