When your Farmall Cub starts flooding the carburetor or won’t maintain a steady idle, chances are the float valve isn’t doing its job. This little valve controls fuel flow into the carburetor bowl, and when it’s worn or stuck, you’ll get everything from fuel leaks to engine stumbling. A properly working float valve keeps fuel at exactly the right level so your Cub runs smooth and doesn’t waste gas.

Built for Real Farm Work
This float valve assembly is designed specifically for International Harvester Cub tractors equipped with carburetor 63349C1. These compact utility tractors were workhorses on small farms and are still popular today for everything from mowing and cultivation to light loader work and general farm chores around the homestead.
Made to Last
Farm equipment sits for weeks sometimes, and fuel issues are common with modern ethanol blends. This float valve assembly uses materials that resist gum and varnish buildup while maintaining a reliable seal. The float won’t absorb fuel over time, and the needle valve maintains its precise fit even after thousands of cycles.
Installation Notes
Installing this assembly requires removing the carburetor bowl and carefully positioning the float and valve components. Make sure the float moves freely and the needle valve seats properly – any binding will cause fuel level problems. Clean out any debris in the carburetor before installing the new parts, and check that the fuel inlet is clear.
