Product descriptionThe 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. We stock the float needle valve (incl. float needle) for the PHB with a diameter of 4.5mm in the sizes 150-225 and with a larger diameter of 5.2mm (incl. spring-loaded float needle) in the sizes 200-400. The speed at which the float chamber is filled increases in proportion to the size of the valve. The float needles (4.5mm and 5.2mm) are also available in- dividually. Please note: The transparent?? and metal?? versions only match the modified screw pa
