Description

If your old Ford tractor has been running rough, struggling to idle, or just doesn’t have the pep it used to, there’s a good chance your carburetor’s main nozzle is worn out or clogged. This little brass fitting controls how much fuel gets mixed with air for combustion, and after decades of use, it can wear oversized or get plugged with varnish and debris. A fresh main nozzle often brings back that smooth, reliable operation you remember.

What You’re Getting

Precision-drilled main fuel metering jet that delivers the right fuel flow
Quality brass construction that resists corrosion and fuel additives
Direct replacement for your original carburetor nozzle
Restores proper fuel mixture for better performance and fuel economy

Built for Real Farm Work

This main nozzle fits the Marvel-Schebler carburetors found on Ford 9N, 2N, and 8N tractors – the workhorses that built American agriculture in the 1940s and 50s. Whether you’re using your Ferguson system tractor for hay work, cultivation, or general farm chores, proper fuel delivery is essential for dependable operation when there’s work to be done.

Made to Last

Brass construction handles today’s ethanol fuels better than the original zinc parts, resisting the corrosion that can plague older fuel systems. The precisely drilled orifice maintains its size over time, ensuring consistent fuel metering season after season.

Installation Notes

This nozzle threads into the main body of your carburetor and requires removing the carburetor bowl for access. While you’re in there, it’s a good time to clean out any sediment and check your float and needle valve. Count the turns when removing the old nozzle so you can start with the same setting.
