Carb Mounting Flange for Ski-Doo Olympique 300

This carb mounting flange replaces the original 4004-1001-00 flange that seats the carburetor to the engine on Ski-Doo Olympique 300 snowmobiles.

Overview

The carb mounting flange for Ski-Doo Olympique 300 is the adapter that joins the carburetor to the engine intake. It seals the joint so the engine draws air through the carburetor instead of leaking around the base.

Good To Know

Q: How do I check the flange for leaks? A: With the engine idling, spray a small amount of carb cleaner around the flange joint. A change in engine note points to a leak that the flange is not sealing.

Q: Should I replace mounting gaskets at the same time? A: Yes, fresh gaskets on both sides of the flange help the joint seal properly. Reuse of old hardened gaskets often brings the leak back.

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