The Multiquip 843365 Main Jet Left (HHNG5) is a genuine OEM carburetor component designed for the HHNG5 Whiteman ride-on power trowel. As a direct OEM replacement, this jet is manufactured to the exact flow calibration required by the HHNG5 engine, ensuring the air-fuel mixture is delivered at the correct ratio for consistent power output. This part is confirmed for HHNG5 series machines, making it a straightforward service replacement for field technicians and equipment owners alike. Sourced directly through authorized Multiquip supply channels, the 843365 carries full OEM traceability.
Key Features
- Exact Flow Calibration: — Manufactured to OEM fuel-metering specification for the HHNG5 carburetor, maintaining the correct air-fuel ratio the engine depends on.
- Left-Side Carburetor Fitment: — Engineered specifically as the left main jet for the HHNG5, dropping directly into position without any adaptation.
- Confirmed HHNG5 Compatibility: — Verified fit for Whiteman HHNG5 ride-on power trowels — cross-reference part number 843365 before ordering.
- Consistent Engine Response: — A correctly sized main jet sustains smooth throttle response and full-power operation throughout the finishing pass; a worn or blocked jet causes erratic RPM and loss of blade speed.
- Genuine OEM Part: — Supplied as an authentic Multiquip OEM component, backed by authorized distribution through DHS Equipment.
The main jet is a precision-metered orifice inside the carburetor that controls the volume of fuel delivered to the engine under normal and high-load operating conditions. Its bore diameter is calibrated to a specific flow rate — too small and the engine runs lean, overheats, and loses power; too large and it runs rich, fouling plugs and wasting fuel. On a ride-on power trowel like the HHNG5, where consistent blade speed directly affects surface finish quality, a correctly functioning main jet is essential to keeping the engine in its optimal power band throughout the pour.
