The fuel comming from the pipe is probably just unburnt fuel sitting in the pipe.
actually, depends on the position of the piston. if the piston is right at the bottom of the intake port, then the fuel can fill up a small portion of the cylinder and flow right into your exhaust port. happened to me once when my petcock failed.

most likely cause is unburnt fuel from a rich mixture, though, like Venice said, unless it's a lot of fuel.
