The Wacker Neuson Main Jet is a genuine OEM component designed for the CRT36-25 915mm/36in Ride-on Trowel, including configurations equipped with the Wheel Kit. As a genuine OEM part, the is manufactured to the exact tolerances required for proper fuel metering in the carburetor — ensuring the engine receives the correct air-fuel mixture under load. This is a direct-fit replacement for CRT36-25 machines and slots into place without modification to the carburetor body. Keep a spare on hand to get your trowel back to work fast when a worn or clogged jet pulls the engine off its tune.
Key Features
- Exact Fuel Metering Tolerance — Genuine OEM construction means the orifice diameter matches the original specification, delivering consistent fuel flow at the correct rate for this engine.
- Direct Carburetor Drop-In — Threads directly into the carburetor body on CRT36-25 machines, using the same thread pitch and seat profile as the part it replaces.
- Confirmed CRT36-25 Fitment — Compatible with both the standard 915mm/36in Ride-on Trowel and the CRT36-25 variant equipped with the Wheel Kit.
- Restores Full Engine Power — A correctly sized main jet keeps the engine running at rated power through the full finishing pass; a worn or clogged jet causes rich or lean conditions, rough idling, and loss of trowel speed.
- Fuel System Integrity — Using the correct OEM-spec jet prevents unmetered fuel delivery that can foul plugs, damage the engine, or create unsafe running conditions on a ride-on machine.
The main jet is a small but critical precision component inside the carburetor responsible for metering the volume of fuel drawn into the engine at full throttle. The size of its orifice is calibrated specifically to the engine's displacement and air flow, so even minor deviation — through wear, damage, or an incorrectly sized replacement — will throw off the air-fuel ratio and cause poor performance, hard starting, or engine damage over time. On a ride-on power trowel working through long concrete finishing cycles, a failed or clogged main jet can bring operations to a halt; replacing it promptly with the correct OEM part restores proper combustion and full machine output.
