The Multiquip 99101ZH70820 Main Jet #82 Optional is a genuine OEM carburetor jet designed for QP402H centrifugal pumps, WM70S/P Whiteman mixers, MC64P/S, MC94P/S, and MC94SK/MC94PK MQ mixer models. As a direct OEM replacement, 99101ZH70820 is manufactured to the same specification as the original component, ensuring proper fuel metering and consistent engine performance across compatible equipment. Verify your model code against the fitment list before ordering to confirm this is the correct jet size for your application.
Key Features
- OEM-Calibrated Fuel Metering: — Sized at #82, this jet delivers the precise fuel flow rate the carburetor was engineered around, maintaining correct air-fuel mixture at operating load.
- Direct Carburetor Drop-In: — Threaded to OEM dimensions for direct installation into the carburetor body with no reworking of the fuel circuit.
- Broad Model Compatibility: — Fits QP402H centrifugal pumps, WM70S/P Whiteman mortar mixers, MC64P/S, MC94P/S, and MC94SK/MC94PK MQ concrete mixers.
- Genuine OEM Part: — Sourced directly from Multiquip, so the orifice diameter, thread pitch, and material grade match the original jet exactly — no guesswork on sizing.
- Restores Clean Engine Operation: — A worn or partially blocked main jet causes rich or lean running, loss of power, and hard starting; replacing it with the correct #82 unit brings fuel delivery back to spec.
The main jet is a small precision-machined orifice located inside the carburetor's main circuit. It controls the volume of fuel drawn into the airstream at mid to full throttle, and its calibrated opening size — in this case #82 — determines the engine's fuel-air ratio under load. When a main jet becomes clogged with varnish or debris, or wears out of spec, the engine runs rough, loses power, or stalls under load. Replacing it with the correct OEM jet restores the fuel metering the carburetor was designed to deliver.
