The Wacker Neuson Main Jet is a genuine OEM main jet designed for the BFS 1318, BFS 1345, and BFS 1350 series gasoline powered floor saws. As a direct factory replacement, this part carries the same specification as the original, ensuring the carburetor meters fuel correctly from day one. It fits a wide range of BFS floor saw configurations including AB, ABZ, A, and AZ variants, covering both standard and zero-turn machine builds. Keep a verified part number on hand — — to avoid fitment errors when ordering.
Key Features
- OEM-Calibrated Fuel Metering: — Manufactured to Wacker Neuson's original orifice specification, so fuel delivery to the engine matches the design intent of your floor saw's carburetor.
- Drop-In Carburetor Replacement: — Threads directly into the carburetor body using the original fitting, requiring no re-jetting or adjustment beyond standard carb reassembly procedure.
- Broad BFS Series Coverage: — Compatible with BFS 1318, BFS 1345, and BFS 1350 floor saw models across AB, ABZ, A, and AZ build variants, spanning multiple production series.
- Consistent Engine Performance: — A correctly sized main jet keeps the air-fuel mixture within spec under load, supporting steady blade speed and clean cutting performance on concrete and asphalt.
- Fuel System Safety Compliance: — Using the correct OEM-specified jet prevents over-rich or over-lean running conditions that can cause overheating, erratic throttle response, or engine damage during cutting operations.
The main jet is a small but critical component inside the carburetor that controls how much fuel is delivered to the engine under normal running load. It works by metering fuel through a precisely sized orifice — too large and the engine runs rich, fouling the spark plug and wasting fuel; too small and it runs lean, risking overheating and power loss. When a main jet becomes worn, clogged, or damaged, the engine will typically stumble under load, surge, or fail to reach full power, making prompt replacement essential for consistent cutting performance.
