The Wacker Neuson Choke Set is a genuine OEM component designed for CT36 and CT48 series walk-behind trowels, PT3A centrifugal trash pumps, BPS 2550A vibratory plates, MPU 29A reversible plates, and HPG series vibratory truss screed power sections. Sourced directly from Wacker Neuson, this choke set matches the original specification exactly, ensuring it seats, seals, and operates just as the engine manufacturer intended. Whether you are servicing a 915mm 36-inch or 1220mm 48-inch walk-behind trowel — including CE and variable-speed variants — this is the correct OEM replacement part. Verify your model number against the fitment list before ordering to confirm compatibility with your specific serial range.
Key Features
- Genuine OEM Fuel System Calibration — Manufactured to Wacker Neuson's original choke specification, so fuel-air mixture at cold start is controlled exactly as the engine was designed to deliver it.
- Drop-In Engine Compatibility — Engineered to align with the original choke bore, linkage, and mounting points, so installation follows the standard service procedure without modification to surrounding components.
- Broad Fitment Across Wacker Neuson Equipment — Confirmed for CT36 and CT48 walk-behind trowel families (including AGP, ADP, AGT, ADT, AVP, and AVT variants), PT3A trash pumps, BPS 2550A vibratory plates, MPU 29A reversible plates, and HPG50/HPG100 vibratory truss screed power sections.
- Consistent Cold-Start Performance — A properly functioning choke set allows the engine to reach operating temperature quickly and cleanly; a worn or stuck choke leads to hard starting, rough idling, and excessive fuel consumption.
- Fuel System Safety Compliance — As a fuel-system component, using the correct OEM part helps ensure the choke assembly meets the original emissions and safety certification requirements for CE-marked machine variants.
The choke set controls the air supply to the carburetor during a cold start, temporarily enriching the fuel-air mixture so the engine fires reliably before it reaches normal operating temperature. Once the engine warms up, the choke opens to restore the correct mixture for efficient running. When the choke set is worn, sticking, or missing components, the engine can become difficult to start in cool conditions, run rough at low speeds, or consume excess fuel — all of which affect productivity on a concrete finishing or pumping job.
