The result is tighter tolerances at the carburetor interface and a part that seals and seats consistently, build after build.\u003c\/p\u003e\u003ch3\u003e\u003cb\u003eInstallation Notes\u003c\/b\u003e\u003c\/h3\u003e\u003cp\u003eDry-fit against your specific carburetor body before final assembly, and torque fasteners evenly in a criss-cross pattern to avoid warping the sealing surface.
