The Honda 16221-883-800 Carburetor Gasket is a genuine OEM replacement designed for a wide range of Honda engines, lawn mowers, snow blowers, tillers, generators, and water pumps — including GC135, GC160, GC190, GCV135, GCV160, GCV190, and GSV190 engines, HRB216, HRB217, HRC216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers, HS520 and HS720 single-stage snow blowers, FG400, FG500, and FR500 tillers, EN2000 and EN2500 generators, and WB20, WB30, WN20, and WN30 water pumps. As a genuine Honda part, it is manufactured to the exact specifications of the original, ensuring a proper seal at the carburetor interface without any guesswork. Confirm the part number 16221-883-800 against your machine's serial number before ordering, as Honda supersedes gasket specifications at production breaks.
Key Features
- Genuine OEM Sealing Integrity — manufactured by Honda to deliver the exact thickness, material composition, and port geometry needed to maintain a fuel-tight seal at the carburetor, preventing air leaks that cause rough running or lean fuel mixture conditions.
- Direct OEM Replacement — engineered to match the original gasket precisely, so this part seats correctly during reassembly without trimming, shimming, or modification.
- Broad Honda Compatibility — fits GC135, GC160, GC190, GCV135, GCV160, GCV190, and GSV190 engines, HRB216, HRB217, HRC216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers, HS520 and HS720 single-stage snow blowers, FG400, FG500, and FR500 tillers, EN2000 and EN2500 generators, and WB20, WB30, WN20, and WN30 water pumps.
- Serial Number Verification Recommended — Honda updates gasket specifications at production serial breaks; always cross-reference part number 16221-883-800 with your machine's serial number using the fitment table to confirm this is the correct version for your unit.
The carburetor gasket forms a critical seal between the carburetor body and the engine intake, preventing unmetered air from entering the fuel-air mixture. Even a small air leak at this joint upsets the carburetor's calibration, causing symptoms such as hard starting, erratic idle, or a lean-running engine that surges under load. When this gasket degrades, compresses, or cracks — typically during carburetor service or after extended heat cycling — replacing it with a correctly sized genuine Honda gasket restores the sealed interface the carburetor depends on to meter fuel accurately.
