Specs At A Glance

Good To Know

Q: How do I know if my carb mounting flange needs replacing? A: Cracks, a hardened surface, or an intake leak that causes erratic idle and lean running are common signs. Inspect the flange face and sealing surface whenever the carburetor is removed.

Q: Does this flange need a gasket? A: A sealing gasket at the mounting face is typical on these assemblies, so inspect and replace it as needed during installation. Tighten the carburetor evenly to avoid distorting the flange.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
