The Honda 16211-ZA0-700 Carburetor Insulator is a genuine OEM Carburetor Insulator designed for GX360 horizontal shaft engines, HT3813 lawn tractors, and HT4213 lawn tractors. As a direct Honda OEM part, it meets every dimension and specification set by Honda at the time of manufacture, making it the straightforward choice for a proper restoration. Verify your machine's serial number against the fitment table before ordering, as Honda periodically supersedes parts at serial number breaks.
Key Features
- Genuine OEM Thermal Spacing — sourced directly from Honda, this insulator delivers the exact spacer thickness and material grade needed to properly isolate the carburetor from cylinder head heat
- Direct-Fit Replacement — built to Honda's original dimensions, this part installs in place of the worn or damaged original without alteration
- Broad Fitment — fits GX360 horizontal shaft engines, HT3813 lawn tractors, and HT4213 lawn tractors; confirm your serial number against the fitment table to ensure this is the correct part for your specific unit
- Engine Performance Protection — a correctly functioning carburetor insulator keeps fuel mixture temperatures stable; a cracked or degraded insulator allows excess heat to reach the carburetor, causing hard starting, rough running, and lean-running conditions
The Carburetor Insulator is a heat-isolating spacer mounted between the carburetor and the cylinder head. Its job is to block engine heat from conducting into the carburetor body, which keeps the incoming air-fuel mixture at a consistent temperature and prevents fuel from vaporizing prematurely inside the carburetor bore. When this insulator cracks, warps, or loses its sealing integrity, excess heat migrates into the carburetor, disrupting fuel metering and causing symptoms such as vapor lock, hard starting, and erratic idle — problems that will persist until the insulator is replaced.
