The Wacker Neuson Main Jet #68 is a genuine OEM carburetor jet designed for a wide range of Wacker Neuson walk-behind concrete trowels and vibratory plate compactors, including the CT36, CT30, WP1540, and WP1550 series. As a direct OEM part, the is manufactured to the exact metering specification of the original jet, ensuring correct fuel-to-air calibration right out of the box. Fitment also extends to select PT2A trash pumps, VPA and VPG series vibratory plates, and HP and SP series vibratory truss screed power sections, making this a broadly applicable service part across the Wacker Neuson lineup. Verify your model number before ordering to confirm compatibility with your specific machine configuration.
Key Features
- Exact Fuel Metering Calibration — Sized at #68, this jet delivers the precise orifice diameter required for correct fuel flow, maintaining the designed air-fuel ratio across the RPM range.
- Genuine OEM Part — Sourced directly from Wacker Neuson, the 5000110590 meets the original carburetor specification — no redrilled passages, no off-spec sizing.
- Drop-In Carburetor Fit — Threaded to match the OEM carburetor body, this jet installs without modification using standard jet removal tools.
- Broad Cross-Family Fitment — Compatible across CT36 and CT30 walk-behind trowels, WP1540 and WP1550 vibratory plates, VPA and VPG plate series, PT2A trash pumps, and HP/SP truss screed power sections.
- Protects Engine Performance — A worn or clogged main jet causes hard starting, rough running, and fuel-rich or lean conditions that accelerate engine wear; replacing it restores clean, consistent power delivery.
The main jet is the primary fuel-metering component inside the carburetor float bowl. It controls how much fuel enters the venturi at mid to wide-open throttle, and its orifice size is calibrated specifically for the engine displacement, air filter, and exhaust configuration of the machine it serves. When the main jet becomes clogged with varnish or debris — or is worn beyond its original diameter — the engine runs erratically, loses power under load, or refuses to reach full throttle. Replacing the jet with an OEM-spec part like the Wacker Neuson 5000110590 restores correct fueling and protects the engine from the damage caused by prolonged lean or rich combustion.
