Key Features
- Genuine OEM Fuel System Accuracy — manufactured to Husqvarna's original specifications, delivering precise metering tolerances critical for consistent fuel delivery in high-demand cutting applications.
- Direct Drop-In Replacement — engineered to match the original valve geometry and port sizing, allowing straightforward installation on the same fuel system connection points.
- Broad Floor Saw Compatibility — confirmed fit for the FS4800D, FS6600D, FS6800D, FS7000DL, FS7000DMT, and FS8400D floor saws, covering multiple models in Husqvarna's professional flat saw lineup.
- Restored Fuel Flow Control — a correctly functioning needle valve maintains stable fuel metering, supporting steady engine output and consistent cutting power through heavy concrete slabs and asphalt.
- Fuel System Integrity — a worn or faulty needle valve can cause flooding, lean running, or hard starting; replacing it with a genuine OEM part restores proper carburetor function and protects downstream fuel system components.
The needle valve is a precision component within the carburetor's fuel metering circuit. It regulates the flow of fuel into the carburetor bowl, opening and closing in response to engine demand to maintain the correct fuel level at all times. When the needle valve wears or fails to seat properly, the engine may flood, run erratically, or refuse to start — issues that bring a floor saw to a halt mid-cut. Replacing a faulty valve with the correct OEM part restores accurate fuel delivery and stable engine behavior across the full range of operating conditions.
