A comprehensive carburetor service kit designed for GY6 125cc and 150cc engine scooters using PD18J or PD19J carburetor specifications — the most common Chinese-manufactured scooter carburetor platform. The kit addresses the most frequent failure modes: hardened or torn diaphragm membrane causing erratic throttle response, worn needle and o-ring causing fuel enrichment, and degraded gaskets causing air leaks at idle. Contents include: full diaphragm membrane, complete gasket set, throttle needle, float needle valve, pilot air screw with spring, and all required o-rings. Suitable for 125cc and 150cc GY6 engines found in Chinese scooters and ATVs.
