The Wacker Neuson Main Jet #65 is a genuine OEM carburetor main jet designed for a wide range of Wacker Neuson CT-series walk-behind concrete power trowels and WP-series single-direction vibratory plate compactors. As a direct factory replacement, part is manufactured to the exact specifications required to maintain proper fuel metering in the carburetor. Compatible machines include the CT30AGT, CT36-5A, CT36ADP, CT36ADT, WP1540A, WP1540AW, WP1550A, and WP1550AW, among other models in these families.
Key Features
- Exact Fuel Metering Orifice — Sized to the #65 specification, this jet delivers the precise fuel-to-air ratio the carburetor requires for correct engine operation across the full RPM range.
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this jet is made from the same brass alloy used in original production, maintaining orifice integrity under repeated heat and fuel-flow cycles.
- Direct Carburetor Drop-In — Threaded to the OEM standard, the 5000110589 seats and torques into the carburetor bowl the same way as the original, with no re-jetting or modification needed.
- Broad Model Coverage — A single part number covers CT30 and CT36 walk-behind trowel families as well as WP1540 and WP1550 vibratory plate families, making it a practical stock item for mixed fleets.
- Protects Engine Performance — A worn or clogged main jet starves the engine of fuel at load, causing lean running, overheating, and power loss; replacing it with a correctly sized OEM jet restores full-load engine output.
The main jet is a small but critical component inside the carburetor's fuel circuit. It contains a precisely drilled orifice that meters the volume of fuel drawn into the airstream when the engine is operating under load. If the jet becomes clogged with varnish or debris — common after extended storage or contaminated fuel — the engine will run lean, lose power, surge, or refuse to reach full RPM. Replacing the main jet with the correct OEM-sized #65 unit restores the calibrated fuel flow the carburetor was designed around, returning the engine to its intended output and protecting it from the damage that lean running causes over time.
