The Multiquip 2796240108 Main Jet is a genuine OEM component designed for B46S90 series walk-behind power trowels. As a factory-sourced part, it meets the exact specifications required by Multiquip for proper carburetor function and consistent fuel metering on your trowel. Sourced directly through authorized channels, this main jet is the correct replacement when restoring engine performance on B46S90 equipment.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured to the exact orifice specification required for correct air-fuel ratio in the B46S90 carburetor, ensuring the engine runs cleanly at operating speed.
- Direct Carburetor Fit — Drops into the carburetor bore using the original thread pitch and jet seat, with no modification to the carburetor body needed.
- B46S90 Trowel Compatibility — Confirmed fitment for the Whiteman B46S90 46-inch walk-behind power trowel series.
- Consistent Power Output — A correctly sized main jet keeps the engine in its optimal power band during finishing passes, preventing the rich-running or lean-running conditions that cause blade speed fluctuation.
- Fuel System Safety — A worn or damaged main jet can cause uncontrolled fuel delivery; replacing with a genuine OEM unit restores predictable throttle response and safe engine operation.
The main jet is a precisely sized brass orifice seated inside the carburetor that meters the volume of fuel delivered to the engine under load. Its calibrated bore diameter controls the air-fuel mixture at mid to full throttle, directly affecting engine power, response, and combustion efficiency. When a main jet becomes clogged, eroded, or damaged, the engine will run rough, lose power, or stall under load — making prompt replacement essential to keeping the trowel performing through a full concrete finishing cycle.
