The Multiquip 16562ZE3700 Throttle Spring GX340 is a genuine OEM component designed for GA6HZ, GA6HB, GA6HEB, GAW180HEA, GAW180HE1, and GAW180HE series gasoline-powered generators and arc welders. As a direct OEM replacement, this spring is sourced to the same specification as the original, ensuring consistent throttle response and carburetor function across all compatible models. Sourcing the correct OEM spring matters — an improperly rated or worn throttle spring will affect governor response and engine speed stability, making part number accuracy critical. DHS Equipment supplies this part with verified fitment to help you get the right component the first time.
Key Features
- OEM-Spec Spring Tension — Engineered to the correct load rating for the GX340 engine throttle linkage, maintaining consistent carburetor actuation under varying load conditions.
- Drop-In Replacement — Mounts to the existing throttle linkage assembly on GX340-equipped machines without modification, using the original attachment points.
- Broad Fitment Coverage — Compatible with GA6HZ, GA6HB, GA6HEB, GAW180HEA, GAW180HE1, and GAW180HE generator and welder models.
- Stable Engine Speed Control — A correctly tensioned throttle spring allows the governor to maintain set RPM under load; a fatigued or broken spring causes surging, hunting, or loss of output regulation.
- Fuel System Integrity — Proper throttle spring function is essential to safe, predictable engine operation on generator and welder applications where stable output voltage and amperage depend on consistent engine speed.
The throttle spring on a GX340-equipped generator or welder connects the throttle lever to the carburetor butterfly, working in tandem with the governor to maintain a set engine speed as electrical or welding load changes. When the spring loses tension or breaks, the throttle linkage becomes unresponsive or erratic, causing the engine to surge, hunt, or fail to hold the RPM needed to deliver stable power output. Replacing a worn or damaged spring restores precise governor control and keeps the machine producing consistent voltage or welding current.
