The Honda 16212-ZL8-000 Insulator Gasket is a genuine OEM component designed for a wide range of Honda engines and power equipment, including GC135, GC160, GC190, GCV135, GCV160, GCV190, GS160, GS190, and GSV190 engines, EN2000 and EN2500 generators, FG400 and FG500 tillers, WN20 and WN30 water pumps, HS520 and HS720 single-stage snow blowers, and HRB216, HRB217, HRC216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers. As a genuine Honda part, this gasket is manufactured to the same standards as the original, ensuring a correct seal between the carburetor and the intake without modification. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks and the correct part number varies by production run.
Key Features
- OEM Sealing Integrity — manufactured to Honda's original specification, this gasket delivers the same carburetor-to-intake seal as the part that left the factory, preventing air leaks that cause rough running, lean fuel mixture, and hard starting.
- Broad Genuine OEM Fitment — covers an extensive range of Honda horizontal and vertical shaft engines, walk-behind lawn mowers, single-stage snow blowers, generators, tillers, and water pumps under one part number 16212-ZL8-000.
- Direct Drop-In Replacement — this gasket installs exactly as the original, with no trimming or adaptation, restoring the carburetor circuit to correct operating condition.
- Verify Serial Number Before Ordering — Honda revises parts at production breaks across this fitment range; check your machine's serial number against the fitment table to confirm part number 16212-ZL8-000 is correct for your unit.
The Insulator Gasket seals the joint between the carburetor and the intake port on the engine, preventing unmetered air from entering the fuel-air mixture. Even a minor air leak at this joint leans out the mixture, causing symptoms such as erratic idle, surging, poor throttle response, and difficulty starting under load. When this gasket hardens, compresses permanently, or deteriorates, the seal is lost and no amount of carburetor adjustment will fully correct the running problem — replacing the gasket restores the airtight joint the carburetor depends on to meter fuel accurately.
