Overview

This carb mounting flange is a direct-fit intake component for the Polaris Classic Touring 800, holding the carburetor firmly against the engine while sealing the joint against vacuum leaks.

Good To Know

Q: How do I know if my carb mounting flange needs replacing? A: Look for cracks, hardening, or a fuel-stained surface around the flange, and check for a hunting idle or lean condition that points to a vacuum leak.

Q: Does this flange require a gasket? A: A gasket is typically used at the mounting surface, so inspect your existing one and replace it if it is compressed or damaged 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.
