I thought that was a bowl drain on the bottom of the bowl. I still don't get this jelly stuff you guys are talking about. Are your fuel lines rated for E10 gas or are they old? Is the jelly stuf black in color?

Oh, and those small screws in the last picture where you have arrows pointing to them with "Drains?" photochopped in... Yes they are the bowl drains and especially with the motor tilted up they will remove all but a drop or two from the carb bowls. There are even little drainage ditches molded into the bottom of the bowl leading to these screws to help them drain more. The larger brass nut is the main jet and it sits higer in he bowl so it won't drain everything.

But still, identify how the water is getting into your tank.
