Description
When your vintage International Harvester starts running rough, missing at idle, or won’t hold a steady RPM, chances are good it’s time to rebuild that Zenith carburetor. These classic tractors from the ’40s and ’50s are still doing real work on farms today, but their carburetors need attention after all these years. This complete repair kit gets your carburetor back to factory specs so your tractor runs like it should.
What You’re Getting
- Complete rebuild kit with all the gaskets, seals, and small parts you need
- Quality TISCO components that match original specifications
- Everything to restore proper fuel flow and air mixture
- Fits both the original Zenith 9752 carburetor and International’s 52499D replacement
Built for Real Farm Work
This kit works on the International Harvester A, B, Super A, and Super AV tractors—workhorses that are still earning their keep on small farms, hobby operations, and restoration projects. Whether you’re using yours for cultivating gardens, running a saw mill, or just keeping a piece of agricultural history alive, a properly rebuilt carburetor makes all the difference in how your tractor performs.
Made to Last
These aren’t cheap aftermarket parts that’ll leave you doing the job again next season. The gaskets and seals are made from materials that can handle today’s ethanol-blended fuels while still working with the original carburetor design. Everything’s sized right and built to restore proper sealing and fuel metering.
Good to Know
Carburetor rebuilding takes some patience, but it’s not rocket science. Clean everything thoroughly before assembly, and don’t over-tighten the small screws—they’ll strip easily. A carburetor rebuild manual specific to your tractor model makes the job go smoother, and having a clean workspace helps keep track of all the small parts.
