Description
Overview:
The Valve Inlet Needle is a Genuine Honda OEM component for the carburettor fuel system on small 4‐stroke engines. It regulates fuel flow into the float chamber, keeping the fuel level correct for clean running and reliable starting. Built with a metal body and a fuel‐resistant sealing tip, it is designed for long service life in regular use. This needle fits popular Honda handheld engines such as the GX25 and GX35 used on brushcutters, hedge trimmers and other light construction and garden equipment. Supplied to Honda specification under part number 16019-ZM3-004 (also 16019ZM3004), it is a direct replacement within the carburettor assembly to restore proper fuel metering and prevent issues such as flooding, fuel starvation, rough idle or hard starting.
