The Multiquip 99101ZN10920 Main Jet #92 Optional is a genuine OEM carburetor jet designed for JWN series mechanical ride-on trowels. Sourced directly from Multiquip, this part meets the original equipment specification for the JWN platform, giving you confidence that it will seat and function correctly. If your trowel's engine is running rich, lean, or inconsistently, swapping to the correct main jet is a straightforward and cost-effective first step toward restoring proper fuel delivery.
Key Features
- OEM-Calibrated Fuel Metering: — Manufactured to the exact jet orifice size of #92, ensuring the correct air-fuel ratio for consistent engine output on JWN trowels.
- Direct Carburetor Drop-In: — Threads directly into the carburetor body in the main jet position, requiring only standard hand tools and no carburetor modification.
- JWN Series Fitment: — Confirmed for JWN mechanical ride-on trowels; use part number 99101ZN10920 to cross-reference against your machine's parts diagram before ordering.
- Optional Tuning Specification: — Designated as an optional jet size, making this the correct choice when re-jetting is needed to address altitude, load, or fuel type variations.
- Fuel System Integrity: — A correctly sized main jet prevents fuel starvation or flooding conditions that can cause hard starts, loss of power, or engine damage during extended troweling operations.
The main jet is a small brass metering component inside the carburetor that controls how much fuel enters the engine under normal operating load. Its precisely drilled orifice governs the air-fuel mixture, and even minor wear, clogging, or an incorrect jet size can cause noticeable performance problems including rough running, black smoke, or power loss. Replacing a worn or incorrect jet with the properly sized OEM unit restores the engine's designed fuel curve and keeps the trowel running smoothly through demanding finishing work.
