Good To Know

Q: What does a carb mounting flange do? A: It seals the connection between the carburetor and the engine intake so the engine draws air only through the carb. A worn flange can cause vacuum leaks and poor running.

Q: How do I know if my flange needs replacing? A: Cracks, hardening, or gaps in the flange often show as rough idle or lean running. Inspect the flange whenever you service the carburetor.
