Frequently Asked Questions
The rubber flange adapter creates a sealed, vibration-dampening interface between the carburetor and intake manifold. It prevents air leaks and reduces vibration transmission.
Signs include vacuum leaks (rough idle, poor performance), visible cracks or deterioration in the rubber, fuel leaks around the carburetor base, or difficulty maintaining carburetor synchronization.
Not recommended. Rubber degrades over time and loses its sealing properties. A new adapter ensures proper fuel delivery and engine performance.
This adapter is designed for Mikuni FHS42 carburetors. Verify your carburetor model matches before purchasing. Consult your service manual or contact a Mikuni distributor.
Yes, it's best practice to replace all gaskets and seals when disassembling the carburetor-to-manifold interface to ensure a proper seal.
