Description
Overview:
This Genuine Honda OEM diaphragm assembly is designed for the carburettors fitted to Honda GX22 and GX31 mini 4-stroke engines. It regulates fuel delivery inside the carburettor so the engine starts easily, idles steadily, and runs smoothly under load. Built from a fuel‐resistant elastomer membrane with a rigid backing plate, it replaces worn or hardened diaphragms that can cause surging, stalling, or poor throttle response. As an exact Honda service part, it matches the original specification for fit and function, helping restore factory performance without guesswork. Supplied under Honda references 16013-ZM3-004 and 16013ZM3004, it suits handheld garden and light construction tools powered by these engines, including brush cutters, hedge trimmers, and small utility equipment where reliable fuel metering is essential.
