The Wacker Neuson Main Jet is a genuine OEM main jet designed for the BFS 1318, BFS 1345, and BFS 1350 series petrol floor saws. Sourced directly from Wacker Neuson, this is the exact production part your machine was built with, ensuring correct fuel metering from the moment it is installed. It fits a wide range of BFS floor saw configurations including AB, ABZ, A, and Az variants across multiple serial number ranges. If your floor saw is running rich, lean, or failing to hold a steady throttle response, replacing the main jet with part number is the correct first step.
Key Features
- OEM-Calibrated Fuel Orifice — Manufactured to the exact bore diameter specified for these engines, delivering the correct air-fuel ratio across the full throttle range.
- Direct Carburetor Drop-In — Threads directly into the carburetor body using the original pitch and size, requiring only standard hand tools to swap out.
- Broad BFS Series Coverage — Compatible with BFS 1318, BFS 1345, and BFS 1350 floor saws across AB, ABZ, A, and Az build variants.
- Steady Engine Performance — A correctly sized main jet keeps the engine pulling cleanly under load, preventing the flat spots and surging that a worn or blocked jet causes during cutting passes.
- Fuel System Integrity — Using the OEM-specified jet maintains correct mixture strength, protecting the engine from lean-run damage that can score cylinder walls and shorten engine life.
The main jet is a small precision-machined orifice located inside the carburetor that meters the flow of fuel into the engine's air stream at mid to full throttle. Its calibrated bore size determines how much fuel reaches the combustion chamber, making it one of the most critical factors in engine response and efficiency. When a main jet becomes clogged with varnish deposits or wears oversize, the engine will either starve for fuel under load — causing power loss and overheating — or run excessively rich, fouling the spark plug and increasing fuel consumption.
