As you may already know, when doing a carburetor clean on any of the taotao model scooters you will find broken off float bowl screws. This is a big problem if you are trying to clean your carburetor. WHY WOULD THEY DO THIS? simple answer. They want to sell more carburetors!! I know bullsh&*! I will show you exactly how to remove these screws with out replacing the carburetor. once thing to note. The taotao carburetors also have the fuel adjustment screw blocked off. If you plan to do any upgrades I would recommend replacing the carburetor.
