3.5 dual carbs dumps fuel out lines

I have a D90 and there are spill lines off each carb which sometime expell fuel. What is this about?

The parts manual calls these "vent pipes". My 110 has them as well. I can't give you the mechanical reason as to why they are there, but I'm sure someone else will chime in who can.

Most days, nothing comes out of them. In warmer weather, or after a long road trip, they will leave a couple drops of fuel on the garage floor. As long as you're not gushing fuel from them, you're fine.

Cheers,

Mike

Carb float valve is sticking allowing excess fuel to overfill the fuel reservoir.
