YAMAKATO GCV160 Carburetor Gasket Set Kit for Honda HRR216 HRX217 GCV190 GSV190 GCV135 GC160 HRS216 HRT216 HRB216 HRB217 HRZ216 Engine Toro Lawn Boy Mower

What It Is

This is a replacement gasket set for the carburetor on Honda GCV160, GCV190, GC160, and similar small engines. It includes the bowl gasket, insulator gasket, and other seals needed to fix fuel leaks or poor running after disassembling the carb for cleaning.

Fitment & Compatibility

Before buying, confirm your engine’s model number (stamped on the engine shroud, not the mower deck). This kit fits Honda GCV135, GCV160, GCV190, GC160, GSV190, and the GXV120/160 family. It also works on Toro and Lawn Boy mowers with these engines. This is an aftermarket kit, not genuine Honda. Check that your carburetor uses a bowl gasket of about 1.5” outer diameter—if you have a different carb style (e.g., fixed-jet or EPA-sealed), this won’t fit. No deck size check needed; it’s engine-specific.

Key Things to Know

• Quality is decent for the price – The gaskets are slightly thinner than OEM, but most users report a good seal if the mating surfaces are clean.
• Installation is straightforward – Requires a screwdriver, no special tools. Clean old gasket residue thoroughly or it will leak.
• Common gotcha – The small O-ring for the fuel shutoff valve is easy to miss or lose. Keep track of it during disassembly.
• Not a carb repair kit – This does not include jets, needles, or diaphragms. Only gaskets and seals.

Should You Buy It

Buy this if you’re doing a basic carburetor clean or rebuild on a Honda GCV/GC/GSV engine and want a cheap, functional gasket set. It’s fine for DIYers and one-time fixes. If you need exact OEM fit or are rebuilding a commercial-use mower, spend a few dollars more for genuine Honda gaskets.
