The Multiquip 99101ZN10980 Main Jet #98 Optional is a genuine OEM carburetor jet designed for JWN series mechanical ride-on trowels. This optional jetting component allows operators to fine-tune the fuel-air mixture delivered through the carburetor, making it especially useful when adjusting for altitude, temperature, or specific operating conditions. As a direct Multiquip OEM part, 99101ZN10980 is manufactured to the exact specifications required by JWN trowels, ensuring a correct fit and consistent carburetor function.
Key Features
- OEM-Calibrated Fuel Metering: — Sized to a precise #98 flow rating, delivering an exact fuel volume through the carburetor circuit for consistent engine response.
- Optional Tuning Flexibility: — Offered as an optional jet to support altitude or climate-based carburetor tuning without altering core engine components.
- Drop-In Carburetor Fit: — Machined to seat directly in the main jet port of the carburetor used on JWN mechanical ride-on trowels, requiring no modification to the jet bore or body.
- JWN Series Compatibility: — Confirmed fitment for JWN non-overlapping blade mechanical ride-on trowels in the Multiquip lineup.
- Engine Performance Preservation: — A correctly sized main jet keeps the engine running at the proper fuel-air ratio, preventing rich or lean conditions that cause rough running, power loss, or premature engine wear.
The main jet is a small-bore metering component seated inside the carburetor that controls how much fuel is drawn into the engine under load. Its orifice size — in this case #98 — directly determines the fuel-air mixture ratio during mid-range and wide-open throttle operation. When the main jet is worn, clogged, or incorrectly sized for operating conditions, the engine may run rough, surge, lose power, or fail to reach full operating speed — reducing trowel blade performance and finishing quality on the slab.
