Multiquip 99101ZF50920 Main Jet #92 GX240 340K1 HC-3134657

The Multiquip 99101ZF50920 Main Jet #92 GX240 340K1 HC- is a genuine OEM carburetor main jet designed for the GA6HZ gasoline powered generator. As a direct Multiquip OEM part, 99101ZF50920 is manufactured to the exact bore diameter and thread specification required to deliver the correct air-fuel ratio under load. If you are servicing or rebuilding the carburetor on your GA6HZ generator, this is the correct main jet — sized at #92 and compatible with the GX240 and 340K1 engine carburetor configurations referenced under HC-. DHS Equipment stocks genuine Multiquip OEM parts so you can get your equipment back to work without guesswork.

Key Features

• Exact Orifice Sizing: — Drilled to a #92 specification, delivering the precise fuel flow rate the GX240 and 340K1 carburetor requires for consistent engine output.
• Genuine OEM Part: — Sourced directly from Multiquip, this jet matches the original HC-3134657 carburetor assembly — no measuring, sizing, or substitution needed.
• Confirmed GA6HZ Fitment: — Engineered specifically for the GA6HZ gasoline powered generator; verify your carburetor reference against HC-3134657 before ordering.
• Restores Proper Fuel Metering: — A worn or clogged main jet causes rough running, surging, or hard starts; replacing it with the correct #92 jet restores stable combustion and full power output.
• Fuel System Integrity: — Using the correct OEM-spec jet prevents lean or rich running conditions that can damage engine internals over time, protecting your investment in the machine.

The main jet is the primary metering component inside the carburetor float bowl. Its precisely drilled orifice controls how much fuel enters the engine under normal operating load — too small and the engine runs lean and hot; too large and it runs rich, wastes fuel, and fouls the spark plug. Over time, main jets can become partially blocked by varnish deposits from stale fuel or wear slightly out of spec, both of which cause noticeable performance problems including surging, loss of power, or difficulty reaching rated output. Replacing the main jet with a correct OEM-spec part like the Multiquip 99101ZF50920 restores accurate fuel delivery and brings engine performance back to where it should be.
