Specs At A Glance

Good To Know

Q: How do I know my flange needs replacing? A: Cracks, hardening, or a lean-running condition at idle often point to a failing flange, so inspect it during any carburetor service. A leak here can cause inconsistent idle and poor throttle response.

Q: Does this include mounting hardware? A: This listing covers the flange itself, so reuse your existing fasteners unless they show damage. Confirm your model and year match before fitting.

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