I think I got a keeper. Changed out all fluids, filters and cleaned all screens. I do have to change coolant yet but waiting on an overflow bottle, this one is rotten. After bleeding all the old fuel and filling all filters I cranked it for about 5 seconds, no start. So I pumped the lift pump again and about 5 seconds later it runs like a new one. Everything major works as it should. I do need small items that are missing or neglected and some small repairs. The tractor is a '97 model and the inner air filter has a date of '98, lol. I think because the filter says "do not wash" it was good to go.
