After rebuilding my carburetor it became clear that the fuel line was clogged. I ordered a new fuel line and in the process of removing the fuel from the tank I discovered this gunk in the tank.
I used the instructions I found over at ScooterHelp.com to remove the tank and the fuel line. That guy is awesome just FYI.
So, today I order a whole new gas tank and fuel tap. Stay tuned for my next installment.
