Rust is the oxidation process when ferrous metals react to oxygen and or water. The rust is forming either by water getting into the carb from setting for long periods of time or rust inside the gas tank is getting through the three screens in the fuel system, or both. Preventative Maintenance is a must on these vintage Ford Tractors. The Manual states if the tractor is to be idle for 30 days or more, the entire fuel system including the tank should be drained and every 60 working hours, the carburetor and fuel line drained. The carburetor has a drain plug on the bottom and removing it then opening the Sediment Bulb Valve all the way to the RESERVE setting will let old gas and condensation in the carb flow out. Additionally, three inline filters need to be cleaned regularly as well. The carburetor fuel line inlet brass elbow holds one of them and you need to remove the fuel line first then unscrew it from the carb. The other two are in the Fuel Sediment Bulb assembly. One can be cleaned by loosening the bail fastener on the bottom, removing the glass jar and dumping out the fuel in there and cleaning it good, then the large brass fine mesh screen can be cleaned or replaced. Reassembly should include a new screen but a new cork gasket should be installed now as well. Some new aftermarket gaskets are made of rubber and I've had leaking issues with them so I use the original cork style gaskets and never have leaks. Here are some pages from the Ford-Ferguson handbook on operation and care.
