I notice the C can have one of two different carbs.
Zenith 61AJ7 or 161J7
How do you know which one your tractor has?
It is very rusty so if marked will take some serious cleaning.
Thanks you

Zenith Carburetors have a disc riveted to the top of the fuel bowl about the size of a dime. There will be two numbers on it. The inside number closest to the rivet is the Zenith P/N, (usually 4 numbers and possibly a letter) and the number on the outside of the disc is the AC number. The AC P/N is 6 digits. ie-212845, 225622 etc. Either number will net you any parts you would need for it along with a Carb kit etc. We have Carb kits in stock along with parts, and also offer Carburetor rebuilding services to.
