Good To Know

Q: How do I know if my carb mounting flange needs replacing? A: Cracks, hardening, or a lean condition at idle usually point to a worn flange. A spray test around the boot while the engine runs can reveal a leak.

Q: Does this flange require new gaskets or clamps? A: Reusing worn clamps or gaskets can cause leaks even with a new flange. Inspect and replace them during installation.

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