Re: Gas pouring out of bottom of air filter. Help.
I'm going to guess that, since you were riding it during this fuel splash episode, the leak is external.
If the carb had over-filled, the engine would have flooded...and no more go!
Check the petcock seal at the tank.
Check the fuel line from the tank petcock to the carb...Is it brittle? Is it loose? Fuel will run downhill leaving you to believe that you have a leak at the carb.
