The Multiquip 16166ZJ0831 Main Nozzle AR13H is a genuine OEM component designed for AR13HA/HAR, AR13H, and AR13HC walk-behind asphalt rollers, as well as the GA9.7HE gasoline powered generator. As a direct Multiquip OEM part, 16166ZJ0831 is manufactured to the exact specification of the original, ensuring correct fuel metering and consistent engine performance across all compatible models. This nozzle ships as a direct, drop-in replacement for the AR13H series carburetor, so your machine returns to full operation without guesswork. Sourced through DHS Equipment as an authorized Multiquip parts distributor, you can order with confidence that you are receiving the correct part for your equipment.
Key Features
- OEM-Calibrated Fuel Delivery — Manufactured to the original Multiquip specification, this main nozzle meters fuel at the precise flow rate required by the AR13H series engine for stable idle and full-throttle response.
- Direct Carburetor Drop-In — Engineered to seat and seal exactly as the factory nozzle, eliminating the need for adjustment or modification during installation.
- Broad AR13H Series Compatibility — Confirmed fitment for AR13HA/HAR, AR13H, and AR13HC rollers and the GA9.7HE generator, covering the core AR13H equipment family.
- Protects Engine Tune and Fuel Efficiency — A worn or clogged main nozzle causes rich or lean running conditions, leading to poor compaction performance, hard starts, and increased fuel consumption; replacing it restores the correct air-fuel mixture.
- Genuine OEM Part Number Verified — Part number 16166ZJ0831 matches Multiquip's published parts documentation, so you can cross-reference against your service manual before ordering.
The main nozzle is a precision-drilled jet housed inside the carburetor body that controls how much fuel is drawn into the airstream at mid-range and full throttle. Its calibrated orifice size determines the engine's air-fuel ratio, which directly affects power output, fuel economy, and emissions compliance. When the nozzle becomes worn, varnished, or blocked — common in equipment that sits between seasons — the engine will stumble under load, run rough, or refuse to reach full RPM, all of which reduce the compaction or generating output the machine is rated to deliver.
