The Wacker Neuson Main Jet is a genuine OEM carburetor component designed for a wide range of Wacker Neuson CT48 series walk-behind concrete trowels, G and GS series portable generators, and RS800A/RSS800A single-drum vibratory rollers. As a direct factory replacement, this main jet is manufactured to the same specification as the original, ensuring the engine receives the correct fuel-to-air ratio for consistent operation. Fitment covers CT48AGP, CT48AGT, CT48AGP-E, CT48AGT-E, CT48AVP, CT48AVT, and CT48-11A trowels, along with G4.6A, G5.6A, G5.7A, GS4.6A, GS5.6A, GS5.7A, and related generator variants. Confirm your model number before ordering to ensure compatibility with your specific machine configuration.
Key Features
- Genuine OEM Fuel Metering Precision — Manufactured to Wacker Neuson's original orifice specification, delivering the exact fuel flow rate the carburetor was designed around.
- Drop-In Carburetor Fitment — Threads directly into the carburetor body using the original seat and thread pattern, requiring only standard hand tools to swap out.
- Broad Model Coverage — Fits CT48 walk-behind concrete trowels, G/GS portable generators (4.6A–5.7A class), and RS800A/RSS800A single-drum rollers across multiple machine configurations.
- Restores Proper Air-Fuel Mixture — A worn or clogged main jet causes rough running, hard starts, or power loss under load; replacing it returns the engine to its correct operating mixture.
- Fuel System Integrity — Using the correct OEM-spec jet prevents over-fueling or lean-running conditions that can cause premature engine wear or carburetor damage over time.
The main jet is a small brass metering component inside the carburetor that controls how much fuel is drawn into the engine during mid-range and wide-open-throttle operation. Its precisely sized orifice determines the fuel-to-air ratio the engine runs on — too large 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 varnish deposits from stale fuel or suffer erosion that enlarges the orifice, both of which disrupt engine performance and make it difficult to maintain steady power output.
