The Wacker Neuson Pilot Jet Size #50 is a genuine OEM carburetor jet designed for BFS 130RM, BFS 130R, BFS18D, BFSX 130RM, BFSX 130R floor saws, and VP1340R, VP1340RW, VP1550R, VP1550RW, and VP2050R vibratory plate compactors. As a genuine Wacker Neuson OEM part, the is manufactured to the exact specification of the original component, ensuring correct fuel metering at idle and low throttle. This jet governs the air-fuel mixture during the pilot circuit, which directly affects cold starting performance, idle stability, and low-speed throttle response. If you are experiencing rough idling, hard starting, or stumbling at low RPM on your BFS floor saw or VP plate compactor, a worn or incorrect pilot jet is a common root cause.
Key Features
- Exact Orifice Sizing for Proper Fuel Metering — The #50 size designation specifies a precise fuel flow rate through the pilot circuit; using an incorrect size will cause lean or rich running conditions at idle.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this jet matches the original carburetor specification for correct fit and function in compatible BFS and VP models.
- Broad Fitment Across BFS and VP Families — Confirmed fit for BFS 130RM, BFS 130R, BFS18D, BFSX 130RM, BFSX 130R floor saws, and the VP1340R, VP1340RW, VP1550R, VP1550RW, and VP2050R vibratory plate compactors.
- Restores Idle Quality and Cold-Start Performance — A correctly sized pilot jet ensures smooth idle, stable low-speed running, and responsive throttle transition — critical for operator control in both cutting and compaction applications.
- Fuel System Integrity — An improperly sized or damaged pilot jet can cause uncontrolled engine behavior at idle; using the correct OEM-specified jet supports safe, predictable engine operation during machine startup and low-load use.
The pilot jet is a small but critical component inside the carburetor's pilot circuit, responsible for delivering the correct amount of fuel when the engine is at idle or operating at low throttle. It works alongside the main jet, with the pilot jet taking over at low RPM where the main jet has little effect. When the pilot jet becomes clogged, worn, or is replaced with an incorrect size, the engine will typically exhibit hard starting, unstable idling, or a stumble when transitioning from idle to partial throttle. Replacing it with the correct Wacker Neuson 5000077420 restores proper fuel delivery and smooth engine operation across all low-speed conditions.
