Wacker Neuson 5000226566 Jet Main #105

The Wacker Neuson Jet Main #105 is a genuine OEM component designed for the RD12A-90 tandem roller series, GV7003A and GV7000A 50Hz portable value generators, and PT4A and PT4A(I) series equipment. As a factory-sourced part, the is manufactured to the exact specifications Wacker Neuson requires for correct fuel metering across all compatible machines. Sourcing a genuine OEM jet ensures the carburetor delivers the right fuel-to-air mixture the engine was calibrated to run on. Verify your model number before ordering to confirm fitment against your specific machine configuration.

Key Features

• Exact OEM Fuel Metering Orifice — Manufactured to the precise bore diameter Wacker Neuson specifies, so fuel delivery matches the engine's original calibration without adjustment.
• Direct Carburetor Drop-In — Threads directly into the main jet port of the OEM carburetor with no re-jetting, resizing, or adaptation required.
• Broad Cross-Equipment Fitment — Covers the RD12A-90 double-drum roller series, GV7003A and GV7000A 50Hz portable value generators, and PT4A and PT4A(I) pumps from a single part number.
• Consistent Power and Throttle Response — A correctly sized main jet keeps the engine running at its designed output across the full throttle range; a worn or blocked jet causes lean running, power loss, and hard starting.
• Fuel System Compliance — Using the OEM-specified jet size keeps the fuel system operating within the emissions and performance parameters the machine was certified to meet.

The main jet is the precisely drilled metering component inside a carburetor that controls how much fuel enters the engine under mid-to-full throttle conditions. Its orifice size is calibrated specifically to the engine displacement and intended operating load, making it one of the most tolerance-sensitive parts in the fuel system. A jet that is blocked, corroded, or replaced with an incorrect size will cause the engine to run lean or rich, resulting in loss of power, overheating, rough running, or difficulty starting — symptoms that directly affect productivity on the jobsite.
