The Wacker Neuson Main Jet is a genuine OEM Main Jet designed for the GP3800 and GV3800 portable generator series and the BFS735 gasoline powered floor saw. Sourced directly from Wacker Neuson, this part carries the same specifications as the component installed at the factory, ensuring a correct, trouble-free installation. Compatibility extends across multiple GP3800A and GV3800A configurations — including standard, premium, and wheel kit variants — as well as BFS735 and BFS735A floor saw models. When your original Main Jet is worn, clogged, or damaged, replacing it with the genuine OEM restores proper fuel delivery and keeps your equipment running at the correct air-fuel ratio.
Key Features
- OEM-Calibrated Fuel Metering Orifice — Machined to the exact bore diameter specified by Wacker Neuson, so the carburetor delivers the correct fuel volume at every throttle position.
- Direct Carburetor Drop-In — Threads directly into the carburetor body on covered models with no re-jetting, drilling, or adaptation required.
- Broad Model Coverage — Fits GP3800A and GV3800A portable and value generator variants (EPA and CSA) plus BFS735 and BFS735A floor saws, all under a single part number.
- Restored Engine Performance — A correctly sized Main Jet prevents the rich or lean running conditions that cause hard starting, surging, and power loss under load.
- Fuel System Integrity — Using the genuine OEM jet maintains the calibrated fuel flow the carburetor was designed around, which is critical for safe operation of both generator and saw applications where engine speed consistency matters.
The Main Jet is a precisely sized metering component inside the carburetor that controls how much fuel is drawn into the engine at mid to full throttle. Its calibrated orifice determines the fuel-to-air mixture, directly influencing engine power output, fuel efficiency, and smooth running across the RPM range. When a Main Jet becomes blocked with varnish deposits or wears oversized over time, the engine will run erratically, lose power, or fail to start — making prompt replacement with a correctly specified part essential to restoring normal operation.
