The Honda 16211-ZE9-601 Carburetor Insulator is a genuine OEM Carburetor Insulator designed for the GXV340 vertical shaft engine. As a direct Honda OEM component, this part is manufactured to the same specification as the original, ensuring an exact match for position, port alignment, and mounting geometry. If you are servicing a GXV340 engine, confirm your engine's serial number against the fitment table to verify this is the correct part for your production range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Carburetor Insulator meets the original design intent for the GXV340 engine, with no substitutions in geometry or material profile.
- Heat Separation Where It Counts — this spacer sits between the carburetor and the cylinder head, blocking conducted heat from the head from reaching the carburetor body and destabilizing fuel metering.
- Direct OEM Fitment — designed specifically for the GXV340 vertical shaft engine, this part installs in place of the original with no modification to mounting hardware or carburetor positioning.
- Check Your Serial Number — Honda updates part numbers at production breaks, so match your engine's serial number to the fitment table before ordering to confirm part number 16211-ZE9-601 is correct for your unit.
The Carburetor Insulator is a heat-blocking spacer mounted between the carburetor and the engine's intake port on the cylinder head. Its role is to limit the transfer of combustion heat from the cylinder head into the carburetor body — heat that, if left unchecked, can cause fuel to vaporize inside the carburetor before it reaches the engine, leading to hard starting, rough idle, and inconsistent throttle response. When the insulator cracks, warps, or develops a leak, it also allows unmetered air into the intake charge, upsetting the air-fuel mixture and causing the engine to run lean. Replacing a damaged insulator restores the thermal and airtight barrier the carburetor depends on to deliver consistent fuel delivery across the full operating range of the GXV340 engine.
