The float bowl area contains some important components which together form the binding link between the fuel tank and the carburettor. These should be checked on a regular basis as if they are worn or damaged the connection gets leaky and the carburettor will fill up with petrol on an uncontrolled basis. The carburettor then fills up uncontrollably with fuel, overflows and the scooter may have problems firing. The individual components can be exchanged quickly and easily and your scooter starts again on the first kick.
