The Wacker Neuson Pilot Jet Set #40 is a genuine OEM carburetor jet set designed for the GV5000A, GV7000A, GV5003A, and GV7003A portable generator series, as well as the BFS 100 gasoline floor saw. Sourced directly from Wacker Neuson, this OEM component ensures the correct fuel metering calibration your carburetor was engineered to deliver. The #40 pilot jet specification is factory-matched to these engines, so installation drops straight into the existing carburetor without guesswork. If your machine is running rough at idle, hesitating, or stalling under light load, a worn or clogged pilot jet is a common cause — and part number is the correct factory fix.
Key Features
- OEM Fuel Metering Accuracy — Calibrated to the exact #40 orifice specification, ensuring the correct air-fuel mixture at idle and low-throttle operation.
- Direct Carburetor Fit — Threads into the pilot jet circuit of the original carburetor on compatible GV-series generators and the BFS 100 floor saw with no modification to the jet bore or seat.
- Broad GV-Series Compatibility — Confirmed fitment across GV5000A, GV7000A, GV5003A, and GV7003A models, including both 50Hz portable value generator configurations, as well as the BFS 100 gasoline floor saw.
- Restores Clean Idle Performance — A correctly sized pilot jet maintains stable idle speed and smooth throttle response; a clogged or wrong-sized jet causes rough running, stalling, and hard starting.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized Wacker Neuson replacement, carrying the same part number 5000084630 referenced in the original equipment documentation.
The pilot jet is a small, precision-orificed fuel metering component housed inside the carburetor. Its job is to regulate the flow of fuel into the engine at idle and during low-load operation — conditions where the main jet plays little role. Because the orifice is extremely small, it is highly susceptible to partial blockage from fuel varnish or debris, which causes hard starting, rough idling, and unstable engine speed. Replacing the pilot jet with the correct-spec part restores proper fuel delivery and returns the engine to stable, consistent operation.
