3085670 Carb Mounting Flange for Polaris Sport Touring 550 2000-2004

Carb Mounting Flange for Polaris

This carb mounting flange, OEM cross-reference 3085670, mounts the carburetor to the engine intake on Polaris Sport Touring 550 snowmobiles from 2000 through 2004.

Overview

This carb mounting flange for Polaris is the intake boot that joins the carburetor to the cylinder and seals that joint against air leaks. On a Sport Touring 550, a failed flange usually shows as a lean condition, poor idle, or difficult starting, so replacing it restores proper fuel metering. It is a direct-fit replacement for anyone servicing the intake side of their 550 fan engine.

Good To Know

Q: How do I know the flange needs replacing? A: Cracks, hardening, or a torn sealing lip are the usual signs, and a lean-running engine with an erratic idle often points to an intake leak at this part.

Q: Does the flange come with clamps or hardware? A: No, this listing covers the flange itself, so reuse or replace the mounting hardware as needed for your machine.

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