I have a 1976 Evinrude 115. The motor runs fine all day but when I shut it off and tilt the motor up I get gas leaking out of the carbs into the transom which makes a real mess. I never tilt the motor all the way up, I just tilt it up enough so the motor will clear the groung when trailoring. Is there anybody out there that may know what is causing this. It is not effecting the way the motor runs but it just makes everthing back there greasy.<br />Thanks in advance;<br />Jason
