The Multiquip 842740 Pilot Jet (HHNG5) is a genuine OEM component designed for HHNG5 series Whiteman ride-on power trowels. Sourced directly from Multiquip, this pilot jet delivers the precise fuel metering your carburetor depends on for consistent low-speed and idle performance. Correct fitment is confirmed for HHNG5 equipment, making this the straightforward replacement choice when servicing the carburetor on these machines. DHS Equipment stocks this part to keep your trowel back in service without delays.
Key Features
- OEM-Spec Fuel Orifice Sizing — Manufactured to the exact bore diameter specified for the HHNG5 carburetor, ensuring correct air-fuel mixture at idle and low throttle.
- Direct Carburetor Drop-In — Threads directly into the pilot jet port of the HHNG5 carburetor without modification, restoring the original fuel circuit geometry.
- HHNG5 Confirmed Fitment — Specifically validated for the Whiteman HHNG5 ride-on power trowel series; use part number 842740 to confirm before ordering.
- Stable Idle and Low-Speed Response — A correctly sized pilot jet prevents rough idling, lean stumbling, and erratic blade speed at low throttle — common symptoms of a worn or clogged jet.
- Fuel System Integrity — As a precision fuel-circuit component, using the correct OEM jet helps maintain proper emissions calibration and safe, predictable engine operation on the trowel.
The pilot jet is a small but critical brass metering component inside the carburetor that controls fuel flow through the idle and low-speed circuit. It works by allowing a precisely measured amount of fuel to mix with incoming air when the throttle is at or near idle position. When a pilot jet becomes clogged, corroded, or worn beyond its specified orifice size, the engine will struggle to idle smoothly, may stall under light load, or run excessively rich or lean — all of which directly affect the controllability and blade engagement of a ride-on power trowel.
