The Wacker Neuson Main Jet #72 is a genuine OEM carburetor main jet designed for a range of Wacker Neuson GP2500A and GV2500A portable generators, WP1540A and WP1550A vibratory plate compactors, and BFS735 gasoline-powered floor saws. As a direct OEM replacement, part is manufactured to the exact dimensions and flow specification of the original component, ensuring the carburetor meters fuel correctly across the full operating range. This jet is the correct #72 size, making it a precise drop-in service part for any of the compatible machines listed above.
Key Features
- OEM-Calibrated Fuel Flow: — Sized to the exact #72 orifice specification, delivering the correct air-fuel mixture the carburetor was engineered to meter — no guesswork, no rich or lean running conditions.
- Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, this is the same main jet installed at the factory — not a generic substitute with unknown tolerancing.
- Broad Cross-Model Fitment: — Fits GP2500A and GV2500A generators, WP1540A and WP1550A vibratory plate compactors, and BFS735 floor saw variants across multiple production series.
- Restores Full Engine Performance: — A worn or clogged main jet causes rough running, power loss, and hard starting; replacing it with the correct #72 jet restores clean throttle response and steady output.
- Direct Carburetor Service Fit: — Threads directly into the carburetor main jet port with no modification — a standard service interval replacement during carburetor cleaning or rebuild.
The main jet is a precisely sized orifice inside the carburetor that controls how much fuel is drawn into the engine at mid to full throttle. Its small bore diameter is calibrated to deliver the correct fuel quantity for the engine's displacement and air intake — too large a jet and the engine runs rich and sooty; too small and it runs lean, overheats, and loses power. Over time, main jets can become partially blocked by fuel varnish or debris, which starves the engine of fuel and causes performance problems that are often misdiagnosed as ignition faults. Replacing the main jet with the correct OEM-spec #72 part restores accurate fuel delivery and brings the engine back to its intended power output.
