Description
Overview:
This genuine Husqvarna inlet needle is a precision fuel-control component for the carburettor on petrol-powered chainsaws and power cutters. It meters the flow of fuel into the carburettor to keep the mixture stable under load and at idle, helping to prevent flooding or lean running. Built from durable metal with a fuel‐resistant tip to withstand modern unleaded and ethanol‐blend petrol, it is designed for long service in demanding conditions. Suitable for a wide range of models, including Husqvarna 42 and 545, it fits directly in the carburettor's inlet seat and works with the metering lever and diaphragm. Genuine OEM Husqvarna part for assured fit and performance. Manufacturer Part Number (MPN): 503 56 34‐01 / 503563401.
