The Honda 16100-ZJ1-862 Carburetor Assembly (BG22J B) is a genuine OEM carburetor built for GX610 and GX620 horizontal shaft engines. As a factory-original component, this carburetor assembly carries the correct jetting, emulsion tube calibration, and fuel metering circuits Honda specifies for these engines — ensuring the air-fuel mixture is dialed in from the moment the engine starts. Honda supersedes carburetor assemblies at serial number breaks, so confirm your engine's serial number against the fitment table before ordering to make sure part number 16100-ZJ1-862 is the right match for your unit.
Key Features
- Factory-Calibrated Fuel Metering — genuine OEM construction means the jets, needle valves, and circuits meet Honda's original air-fuel ratio specifications for the GX610 and GX620, with no re-jetting or adjustment needed at installation
- Direct OEM Replacement — engineered to mount and connect exactly as the original, using Honda's own part number 16100-ZJ1-862, so installation follows Honda's standard service procedure without modifications
- BG22J B Variant Identification — the (BG22J B) designation identifies this specific carburetor configuration; with multiple carburetor variants listed across GX610 and GX620 production runs, match this code to your engine's serial number to confirm the correct assembly
- Restored Engine Performance — a worn or degraded carburetor causes hard starting, rough idle, and fuel delivery problems; replacing it with this assembly restores clean throttle response and consistent power output across the engine's operating range
The carburetor is responsible for blending fuel and air in the precise ratio the engine needs to run efficiently across all throttle positions. On the GX610 and GX620 horizontal shaft engines, a properly functioning carburetor assembly governs everything from cold-start enrichment to full-load fuel delivery. When a carburetor wears out or becomes fouled — through varnish buildup, damaged needle valves, or clogged jets — the engine stumbles, loses power, runs rich or lean, and may refuse to start altogether. Replacing the carburetor assembly with a genuine OEM unit restores the engine's ability to deliver smooth, consistent power to whatever equipment it drives.
