Description
Overview:
This genuine Husqvarna metering diaphragm (MPN 503 89 67-01 / 503896701) is a thin, fuel‐resistant membrane that controls fuel delivery inside the carburettor. By regulating the metering needle, it keeps the fuel‐to‐air ratio stable for reliable starting, clean acceleration and consistent running. Made from durable elastomer composite suitable for petrol use, it is a direct replacement part designed for small Husqvarna 2‐stroke machines. It is commonly used on chainsaws such as the Husqvarna 136 and 141, and also fits selected trimmers, brushcutters and blowers in the 225, 227 and 240 series. As a genuine part, it maintains factory performance and helps extend the service life of your equipment when carrying out a routine carburettor overhaul.
