When your old Ford tractor starts running rough or won’t hold an idle, the carburetor main needle might be worn out. This little part controls how much fuel mixes with air in your carburetor, and when it’s not sealing right, you’ll know it. You’ll get poor fuel economy, black smoke, or an engine that just won’t run smooth no matter how you adjust it.
What You’re Getting
- Direct replacement needle that matches the original Ford specifications
- Precision-machined tip that seals tight against the needle seat
- Built to handle the vibration and temperature changes of farm work
- Made by TISCO with quality materials that last
Built for Real Farm Work
This needle fits Ford tractors with the 172 cubic inch gas engine—that’s your 801, 901, and early 4000 models from 1958 to 1964. These were solid utility tractors that handled everything from cultivating corn to running a hay baler, and they’re still earning their keep on farms today.
Made to Last
The needle is machined to tight tolerances so it seats properly in the carburetor body. It’s built to handle the constant adjustment cycles and fuel exposure that comes with regular tractor use, so you won’t be doing this job again anytime soon.
Installation Notes
This threads right into your carburetor where the old one came out. Turn it in gently until it seats, then back it out about 1-1/2 turns as a starting point for adjustment. Fine-tune from there based on how your engine runs—a little patience with the adjustment will have your Ford purring like it should.
