Description
When your old tractor starts running rough, hesitates on acceleration, or won’t hold an idle, there’s a good chance the carburetor’s main needle valve isn’t sealing properly anymore. After years of use, that tiny but crucial component wears down and lets too much fuel through—or worse, it sticks and cuts off the fuel supply entirely. This replacement kit gets your Marvel Schebler or TSX carburetor back to running like it should, whether you’re working with a Ford 9N from the 1940s or a 700 series from the 1950s.
What You’re Getting
- Complete main needle valve and packing set that controls fuel flow to the engine
- Quality TISCO construction that’s built to handle decades of farm use
- Precise fit that restores proper fuel metering for smooth engine operation
- All necessary sealing components to prevent fuel leaks and maintain consistent performance
Built for Real Farm Work
This kit works with the Marvel Schebler carburetors found on vintage Ford tractors from the 9N and 2N models through the 600 and 700 series machines. These were the tractors that helped transform American farming in the mid-20th century, and many are still earning their keep on small farms, hobby operations, and restoration projects today.
Made to Last
The main needle valve might be small, but it’s one of the hardest-working parts in your carburetor. This TISCO replacement is machined to original specifications and built to handle the constant opening and closing cycles that come with regular tractor use. The included packing ensures a proper seal that won’t let fuel seep past the threads.
Good to Know
Installing this kit requires basic carburetor disassembly—nothing too complicated if you’re comfortable with small engine work. Clean everything thoroughly while you’ve got the carburetor apart, and check the float and seat while you’re in there. A little carburetor cleaner and compressed air will help ensure your rebuilt carburetor runs smooth for years to come.
