The Multiquip 99101ZH81000 Main Jet (#100) is a genuine OEM carburetor jet designed for SP1CE13H18 and SP118 flat saws and GAW180HE, GAW180HE1, and GAW180HEA gasoline arc welders. As a direct factory replacement, this jet carries the exact bore sizing and flow rating specified by Multiquip, ensuring the air-fuel mixture is metered precisely as the original design intended. Verified fitment across the SP1CE13H18, SP118, and GAW180HE series means no guesswork when sourcing this critical fuel system component. Sourcing the correct OEM jet by part number 99101ZH81000 is the straightforward way to restore proper carburetor function on affected equipment.
Key Features
- Exact Bore Calibration — OEM-specified #100 flow rating ensures the correct fuel delivery volume for the engine's designed operating range.
- Direct Carburetor Drop-In — Machined to the same thread pitch and seat profile as the original, seating cleanly into the carburetor body without rework.
- Broad Series Fitment — Compatible with SP1CE13H18 and SP118 flat saws as well as GAW180HE, GAW180HE1, and GAW180HEA gasoline arc welders.
- Consistent Engine Performance — A correctly sized main jet keeps the engine running at proper power output across the full throttle range; an undersized or oversized jet causes lean or rich running, rough idle, and power loss.
- Fuel System Integrity — OEM construction maintains the tight tolerances that prevent fuel weeping past the jet seat, supporting safe carburetor operation on gas-powered equipment.
The main jet is the precision-metered orifice inside the carburetor that controls how much fuel is drawn into the engine under load. Its bore diameter — designated here as #100 — is calibrated to deliver the correct fuel-to-air ratio at wide-open throttle, directly affecting power output, fuel efficiency, and engine temperature. When a main jet becomes clogged, corroded, or worn oversize, the engine will run roughly, lose power under load, or refuse to reach full RPM — symptoms that can be misdiagnosed as ignition or compression issues until the carburetor is inspected.
