Product Overview
A cracked or hardened carb socket can pull unmetered air into a two-stroke, causing a hanging idle, lean bog, difficult starting, overheating, or piston damage. Flex the old rubber and pressure-test the intake instead of covering the leak with richer jetting.
The flange seals the carburetor to the engine. Match bolt spacing, bore, carb angle, molded shape, and 420867300 because several Ski-Doo twin-cylinder boots look similar.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Can a small boot crack damage a two-stroke engine? A: Yes. Extra air can create a lean mixture and excessive heat under load.
Q: Should both intake boots be inspected? A: Yes. They share the same age and heat exposure even if only one leak is visible.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
