The Honda 16015-ZK7-S91 Float Chamber Set is a genuine OEM replacement designed for GXV160 vertical shaft engines, F401, F501, FC600, FR600, FR650, FR750, and FR800 tillers, HS521 and HS621 single-stage snow blowers, HS522, HS624, and HS724 two-stage snow blowers, and the HP400 power carrier. As a factory-sourced component, this set delivers the exact dimensions and materials Honda specifies for proper carburetor fuel bowl function. Verify your machine's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks and this set may not cover every production run of each listed model.
Key Features
- Genuine OEM Fuel Bowl Integrity — sourced directly from Honda, this set matches the original float chamber's sealing geometry and inlet passages, maintaining correct fuel level and metering in the carburetor bowl.
- Direct-Fit Replacement — engineered to drop into the carburetor assembly without modification, restoring the sealed chamber environment the float and needle valve depend on.
- Broad Cross-Equipment Compatibility — covers GXV160 engines, a range of Honda tillers including the FC600 and FR-series, single- and two-stage snow blowers, and the HP400 power carrier; confirm your model and serial number before ordering.
- Fuel Delivery Performance — a compromised or cracked float chamber causes fuel leaks, inconsistent bowl levels, and rough running or no-start conditions; a sound chamber set keeps fuel delivery stable across all operating loads.
The float chamber — also called the fuel bowl — is the reservoir at the base of the carburetor that holds a small, controlled supply of fuel ready for the engine to draw on. A float riding inside the chamber rises and falls with the fuel level, opening and closing a needle valve to maintain that level within a precise range. When the chamber cracks, warps, or loses its seal, fuel can leak externally or the float mechanism loses its reference level, causing the engine to run rich, run lean, or refuse to start. Replacing the full Float Chamber Set restores the sealed, stable fuel environment the carburetor needs to deliver consistent performance across the GXV160 engine and the wide range of Honda power equipment this part serves.
