The Multiquip 99101ZF50980 Main Jet #98 is a genuine OEM carburetor jet designed for GX240 and 340K1 engine applications. This OEM-sourced component ensures the correct fuel metering orifice size is maintained for accurate air-fuel mixture delivery. Sourced directly through Multiquip, this jet is the exact specification called out for GX240-equipped machines and is confirmed compatible with GX240 series engines. If your equipment is running rich, lean, or stumbling under load, a worn or incorrect main jet is often the cause — this direct replacement restores proper carburetion.
Key Features
- Correct Orifice Calibration — Sized at #98 to maintain the precise fuel flow rate the GX240 and 340K1 carburetor requires for clean combustion across the RPM range.
- Genuine OEM Sourcing — Supplied as an authentic Multiquip OEM part, meaning it meets the exact material and dimensional tolerances of the original production component.
- Direct Carburetor Drop-In — Threaded to the original specification for the GX240 and 340K1 float-style carburetor, seating and torquing exactly as the factory unit did.
- Restores Proper Air-Fuel Ratio — A correctly sized main jet prevents rich fouling, lean surging, and power loss — keeping GX240-powered equipment running at rated output.
- Engine Compatibility Confirmed — Validated for GX240 series engines; cross-referenced to HC-3344652 for additional fitment verification during service.
The main jet is the small, precision-machined orifice inside the carburetor that meters the volume of fuel entering the engine under normal running conditions. Its calibrated hole size determines how much fuel mixes with incoming air — too large and the engine runs rich and sooty, too small and it runs lean and loses power or overheats. Over time, jets can become partially blocked by varnish deposits from stale fuel or physically worn, both of which throw the air-fuel ratio off. Replacing a faulty main jet with the correctly sized OEM unit restores the calibrated mixture the engine was designed to run on.
