The Multiquip 99101ZH70580 is a genuine OEM Main Jet (#58) GX120K1 designed for equipment fitted with the Honda GX120K1 engine. As a direct OEM replacement, this jet is manufactured to the exact sizing and flow specifications required by the GX120K1 carburetor, ensuring the correct air-fuel ratio is maintained under load. DHS Equipment supplies this part direct, so you can confirm fitment by model code and order with confidence. Verify your engine model against GX120K1 before ordering to ensure a correct application match.
Key Features
- Exact Orifice Sizing — #58 Calibration: Manufactured to the precise #58 jet specification, delivering the correct fuel metering the GX120K1 carburetor requires for consistent engine performance.
- Genuine OEM Component: Sourced directly from the OEM supply chain, this jet matches the original part installed at the factory — no guesswork on sizing or thread pitch.
- Direct Carburetor Replacement: Installs directly into the GX120K1 carburetor's main jet port, requiring only standard carburetor tools for removal and installation.
- GX120K1 Engine Compatibility: Confirmed fitment for equipment powered by the Honda GX120K1 engine — cross-reference your engine model code before ordering.
- Restores Proper Fuel Delivery: A worn or clogged main jet causes rough running, loss of power, and poor throttle response — replacing it with a correctly sized OEM jet restores clean, stable engine operation.
- Fuel System Integrity: Using the correct OEM jet size in a fuel system component is critical — an incorrect jet can cause lean or rich running conditions that may damage engine internals over time.
The main jet is a small but critical component inside the carburetor that meters the flow of fuel into the engine at mid to full throttle. Its orifice — in this case sized at #58 — is precision-drilled to control exactly how much fuel enters the air stream, directly affecting engine power, efficiency, and combustion quality. When a main jet becomes clogged with debris or varnish, or is replaced with an incorrect size, the engine will run poorly, surge, or lose power under load, making prompt replacement with the correct OEM specification jet essential for restoring normal operation.
