The Honda 16100-ZH8-H31 Carburetor Assembly (BE07D B) is a genuine OEM replacement built for HS522 and HS622 two-stage snow blowers. As a factory-original component, this carburetor assembly is manufactured to the exact specifications Honda requires for these machines, ensuring correct fuel metering and air-fuel mixture delivery from the first start. Verify part number 16100-ZH8-H31 against your snow blower's serial number before ordering, as Honda supersedes carburetor assemblies at specific serial breaks, and the BE07D B variant designation is the key identifier for this application.
Key Features
- Correct Jetting and Fuel Metering — as a genuine OEM carburetor assembly, this part is calibrated to Honda's exact air-fuel specifications for the HS522 and HS622, not a generalized approximation.
- Direct OEM Replacement — this carburetor assembly is engineered to drop into place on compatible two-stage snow blowers without modification, restoring factory fuel delivery.
- Two-Stage Snow Blower Fitment — designed specifically for HS522 and HS622 two-stage snow blowers; confirm your model and serial number against the fitment table to ensure this is the correct assembly for your unit.
- Serial Number Verification Recommended — Honda updates carburetor assemblies at production serial breaks, so checking your machine's serial number against the compatibility table is the surest way to confirm this is the right part.
- Restored Cold-Weather Starting — a worn or compromised carburetor on a snow blower commonly causes hard starting in cold temperatures, rough running, and poor throttle response; a fresh assembly brings back consistent, dependable ignition when conditions demand it most.
The carburetor assembly is responsible for blending air and fuel in the correct ratio and delivering that mixture to the engine's combustion chamber. On a two-stage snow blower like the HS522 and HS622, reliable carburetion is especially critical because these machines are called upon in cold ambient temperatures where fuel atomization and mixture calibration directly affect starting and sustained performance. When a carburetor wears or becomes fouled — through varnish deposits from stale fuel, worn needle seats, or clogged jets — the engine may refuse to start, idle erratically, surge under load, or lack the power needed to drive the augers and impeller through heavy snow. Replacing the assembly with a genuine Honda unit restores the precise fuel delivery the engine was designed to run on.
