Description
If you’ve ever wrestled with a cold tractor that just won’t start on a frosty morning, you know how important that choke is. This carburetor choke fly assembly—the little butterfly valve that restricts airflow when you pull the choke knob—is what enriches the fuel mixture so your engine fires up when it’s cold. When it gets worn or warped, you’ll be cranking a lot longer than you should be.
What You’re Getting
- 1-5/16″ diameter choke butterfly that fits properly in your carburetor bore
- Complete assembly with shaft and hardware for easy installation
- Direct replacement for original equipment—no modifications needed
- Quality construction that operates smoothly and seals properly when closed
Built for Real Farm Work
This choke fly works with the Marvel Schebler carburetors found on Ford 9N, 2N, 8N tractors, as well as NAA models from 1953-1954 and 600/700 series tractors from 1955-1957 equipped with the 134 CID engine. These are the workhorses that kept farms running for decades—whether you’re using yours for cultivating, hay work, or just keeping the home place tidy.
Made to Last
Farm equipment sits outside in all kinds of weather, and carburetor parts take a beating from temperature swings, moisture, and ethanol in today’s fuel. This choke fly is built to handle the conditions, with materials that won’t warp or bind up when you need that choke to work.
Good to Know
Installation involves removing the carburetor top and carefully positioning the butterfly in the choke bore. Make sure the choke shaft moves freely and the butterfly closes completely when the choke is pulled. A little light oil on the shaft bushings helps keep everything operating smoothly for years to come.
