The Honda 16212-Z8B-900 Insulator Gasket is a genuine OEM component designed for GCV160 vertical shaft engines, HRR216 lawn mowers, and HRS216 lawn mowers. As an authentic Honda part, it delivers the exact fit and sealing performance the original design requires. Confirm your machine's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Sealing — manufactured to Honda's original specification, ensuring the gasket seats correctly and holds a consistent seal between the carburetor insulator and the engine without improvisation or rework.
- Direct-Replacement Fit — engineered as a drop-in replacement for part number 16212-Z8B-900, matching the original dimensions for straightforward installation.
- Broad Honda Compatibility — fits GCV160 vertical shaft engines as well as HRR216 and HRS216 lawn mowers; verify your serial number against the fitment table to confirm the correct application for your unit.
- Prevents Fuel and Air Leaks — a compromised insulator gasket allows unmetered air into the fuel circuit, causing rough running, hard starting, and lean-condition damage; this replacement restores the intended air-fuel seal.
The Insulator Gasket seals the joint between the carburetor insulator block and the engine's intake port, preventing air leaks that would upset the fuel-air mixture the carburetor meters. On GCV160-powered equipment including HRR216 and HRS216 lawn mowers, even a small breach at this joint introduces uncontrolled air into the intake, leaning out the mixture and causing symptoms such as surging, hard starting, or an engine that won't hold a steady idle. Replacing a cracked or deteriorated gasket restores the airtight seal the carburetor needs to regulate fuel delivery correctly.
