The Multiquip 16166ZH8W60 Main Nozzle is a genuine OEM component designed for J-Series, JA-Series, and Epoxy-Series walk-behind trowels. As a direct OEM replacement, this nozzle is manufactured to the same specification as the original, ensuring correct fuel delivery geometry and fitment without the guesswork. Verified compatible with Multiquip J-Series and JA-Series 36-inch walk-behind trowels as well as Epoxy-Series models, the part is a straightforward service part that keeps your trowel engine running at its intended calibration. When it comes time to restore proper fuel circuit function, sourcing the correct OEM nozzle is the most direct path to a confident repair.
Key Features
- OEM Fuel Metering Accuracy — Manufactured to the exact orifice specification of the original nozzle, maintaining the precise fuel-to-air ratio the engine was calibrated for.
- Direct Carburetor Fitment — Engineered to seat and seal correctly within the original carburetor body, requiring no modification to mounting points or fuel passages.
- Broad Walk-Behind Trowel Compatibility — Fits Multiquip J-Series, JA-Series, and Epoxy-Series walk-behind trowels, covering both standard and Quick Pitch handle configurations.
- Restores Full Engine Response — A worn or clogged main nozzle causes lean running, hesitation, and power loss; replacing it with this part restores crisp throttle response and consistent engine output.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain, confirming material grade and dimensional integrity for a service-ready replacement.
The main nozzle is the primary metering component inside the carburetor, responsible for delivering a calibrated volume of fuel into the airstream at mid to full throttle. It works alongside the pilot circuit to ensure the engine receives the correct mixture across the full operating range of the trowel. When the main nozzle becomes worn, blocked, or damaged, the engine will typically run lean, lose power under load, or surge — all conditions that interrupt finishing work and place additional stress on the engine. Replacing it with the correct OEM nozzle restores the carburetor to its original fuel delivery specification.
