The Multiquip 99101ZM30420 is a genuine OEM Jet #42 GX22 GX31SA DSGPU designed for GX22 and GX31SA series equipment. As a direct Multiquip OEM component, this jet is manufactured to the exact specifications required by these engines, ensuring correct fuel metering and consistent carburetor performance. Confirmed fitment covers GX22 and GX31SA powered units, so you can order with confidence knowing 99101ZM30420 is the right part for your application.
Key Features
- OEM-Spec Fuel Metering Orifice — Calibrated to the precise bore diameter specified for GX22 and GX31SA carburetors, maintaining correct air-fuel ratio at all throttle positions.
- Drop-In Carburetor Fit — Threads directly into the carburetor body the same way the original installs, with no reworking of the bowl or jet seat required.
- Confirmed GX22 and GX31SA Fitment — Engineered specifically for GX22 and GX31SA powered DSGPU equipment, eliminating guesswork when sourcing a replacement jet.
- Consistent Engine Response — A correctly sized jet keeps throttle response crisp and fuel delivery stable; a worn or partially blocked jet causes rough running, hard starts, and poor power output.
- Genuine Multiquip OEM Component — Sourced directly through the Multiquip OEM supply chain, so the part you receive matches the original in material grade and dimensional tolerance.
A carburetor jet is a small precision-machined fitting with a calibrated orifice that controls how much fuel enters the engine's air stream at a given throttle position. The orifice diameter is set to a tight specification — in this case, a #42 sizing — so that the fuel-air mixture stays within the combustion window the engine was designed around. When a jet becomes worn, corroded, or clogged with varnish from stale fuel, the mixture shifts rich or lean, leading to hard starting, erratic idle, loss of power, or engine flooding. Replacing the jet with the correct OEM-spec 99101ZM30420 restores the intended fuel delivery and brings engine performance back to normal operating condition.
