Description

When your old International runs rough at idle or you smell gas around the carburetor, chances are it’s time for a new carburetor gasket. A worn gasket lets air sneak in where it shouldn’t, throwing off your fuel mixture and making that reliable old tractor act temperamental. This replacement gasket seals things up properly so your engine runs smooth and steady like it should.

What You’re Getting

Precision-cut gasket that creates an airtight seal between carburetor and manifold
Quality material that resists fuel, oil, and temperature changes
Exact fit for your International’s original carburetor design
Restores proper fuel metering for smooth operation at all RPMs

Built for Real Farm Work

This gasket fits International Harvester tractors with C123 gas engines, including Super A-1, Super AV-1, C, and Super C models, along with 100 and 200 series tractors. These are the workhorses you see pulling cultivators through corn rows, running hay equipment, or powering PTO-driven implements around smaller farms and acreages.

Made to Last

Farm tractors sit outside year-round, and carburetors take the brunt of temperature swings, vibration, and ethanol-blended fuels. This gasket is made from materials that hold up to these conditions, maintaining its seal through hot summer days and cold morning starts. It’s built to handle the constant expansion and contraction that comes with regular use.

Good to Know

Before installing, clean both the carburetor and manifold surfaces with a scraper and carburetor cleaner to remove old gasket material. A thin, even coating of gasket sealer helps ensure a good seal, but don’t over-tighten the carburetor bolts—they can distort the gasket or crack the carburetor body.
