For a guaranteed factory seal, the Genuine Honda 16212-ZL8-000 Insulator Gasket is the standard individual replacement. It is made from high-heat resistant composite material to withstand the extreme temperatures near the cylinder head. Since these gaskets often tear during carburetor removal, the Honda Genuine Carburetor Gasket Set is the most cost-effective choice for repairs. This 4-piece set includes the insulator gasket, the carburetor mounting gaskets, and the air cleaner gasket, ensuring you have everything needed for a leak-free reassembly.
