The Wacker Neuson Main Jet #105 is a genuine OEM carburetor fuel metering component designed for the BFS 2020AS floor saw and the GS12Ai 50Hz portable generator. As a direct Wacker Neuson OEM part, the is manufactured to the exact specification of the original, ensuring correct fuel flow calibration right out of the box. This jet is a critical carburetor component and is confirmed to fit both the BFS 2020AS and GS12Ai model families.
Key Features
- Exact Fuel Orifice Sizing: — Manufactured to the precise #105 orifice specification, delivering the correct air-fuel mixture calibration the carburetor was engineered around.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this jet matches the original component in material grade, threading, and metering diameter — no guesswork on fit.
- Confirmed Cross-Family Fitment: — Compatible with the BFS 2020AS floor saw and the GS12Ai 50Hz portable generator, covering two distinct Wacker Neuson equipment families.
- Restores Proper Engine Performance: — A worn or clogged main jet causes rough running, fuel starvation, and loss of power under load; replacing it with the correct #105 jet restores smooth, consistent engine output.
- Fuel System Integrity: — Using the correct OEM-spec main jet ensures the carburetor operates within designed fuel-delivery parameters, protecting the engine from lean-run conditions that accelerate wear.
The main jet is the primary fuel metering component inside the carburetor. It controls how much fuel enters the engine at mid-to-full throttle by allowing a calibrated volume of fuel to be drawn through its precisely sized orifice. When the main jet becomes clogged, worn, or is replaced with an incorrect size, the engine will run lean or rich — resulting in power loss, hard starting, overheating, or engine damage under sustained load. Replacing a faulty main jet with the correct OEM-spec #105 unit restores the carburetor to its intended operating balance.
