I took my boat out and ran it one last time this year and discovered that it leaks gas out of one of the carbs when I tilt it up to put the bracket on it (on the trailer after it ran and was primed). I have had issues with this in the past and have taken the carbs apart and I usually adjust the float a little and it stops. I need some help....this is about 6 times I have taken these apart and I cannot get the leak to stop. Any suggestions on how to fix this for good?
