Good evening. I just took the tank off of a recently purchased super c. The tank an lines are so full of sludge that nothing will flow through it. the fuel that was in the tank was drained when I took the tank off. The carb was full of rust and white powder. It is a carter car 0-653 i believe. My questions are, what is the best thing to clean the sludge out of the tank? As for the carb, is it worth putting a kit in or just buying a zenith and being done with it? I dont want to make this a show tractor. Just functional. I have seen carbs on amazon for 50 bucks but dont know if it is worth the hassle. Cleaning the tank right now is my main concern. Thanks
