Honda OEM Carburetor Assembly | Select GX390 Models | 16100-Z5T-901

Restore your engine's factory power, smooth idling, and reliable fuel delivery with this genuine Honda OEM Carburetor Assembly. Over time, stale ethanol-blended gasoline varnishes internal jets, causing hard starts, surging, or stalling under load. Cleaning a heavily fouled carburetor often yields temporary results — replacing it with this genuine factory assembly guarantees the correct air-fuel mixture across your entire RPM band.

Includes precision-machined internal floats, premium needle valves, and optimal jet sizing engineered exactly to Honda's strict small-engine tolerances.
