Husqvarna 544200001 Decompression Valve Oem

Product Description

The HUSQVARNA 544200001 is a genuine OEM decompression valve designed to reduce cylinder compression during the starting sequence of small engines. By venting a small amount of cylinder pressure automatically, the valve lowers the force required to pull-start the engine, reducing starter rope fatigue and minimizing kick-back. This part is manufactured to original equipment specifications, ensuring a direct fit and consistent operation. Licensed technicians and service dealers install this valve on Husqvarna outdoor power equipment as part of routine engine maintenance or starting-system diagnosis.

This decompression valve is used in gasoline-powered Husqvarna outdoor power equipment where the engine is equipped with a decompression port on the cylinder head. Typical applications include chainsaws, trimmers, and similar handheld or backpack equipment that rely on a recoil start system. It is the appropriate replacement when the original valve fails to vent, sticks in the open position, or causes hard-starting complaints. No compatibility data beyond the Husqvarna OEM fitment was provided in the source data.

Installation Notes

Installation is typically performed by a small-engine technician or authorized Husqvarna service dealer. Disable the ignition and allow the engine to cool completely before removing any cylinder-head components. Use the correct thread size and torque procedure per the engine service manual to avoid stripping the cylinder-head port. Verify that the new valve moves freely and seals properly before returning the unit to service.
