Description

If your old International is running lean, flooding, or just plain acting up at idle, there’s a good chance that carburetor float has seen better days. These vintage tractors were built to last, but after decades in the field, that float can develop leaks, get waterlogged, or simply wear out. When it’s not doing its job, your fuel mixture goes haywire and you’ll notice it right away.

What You’re Getting

Precision-made replacement float designed specifically for 1-inch updraft carburetors
TISCO quality construction that matches or exceeds original specs
Sealed design that won’t absorb fuel or develop leaks over time
Direct replacement for worn or damaged original floats

Built for Real Farm Work

This float is engineered for the updraft carburetors found on International Harvester’s H, HV, O4, OS4, and W4 series tractors from the 1940s and early 1950s. These were the workhorses that helped feed America—utility tractors that handled everything from cultivating corn to powering hay balers with their reliable gas engines.

Made to Last

Modern materials and construction methods mean this replacement float will likely outlast the original. It’s built to handle the temperature swings and vibration these old tractors dish out, maintaining proper fuel level control season after season.

Installation Notes

Installation is straightforward—just remove the carburetor bowl, unhook the old float assembly, and install the new one. Make sure to check your float level setting when you reassemble everything. If you’re not familiar with carburetor work, this is a good time to have the whole carb cleaned and adjusted by someone who knows these old updraft units.
