I'm going to look at what a guy says is a older(two tone) Case 446 garden tractor but he also tells me that it has a black stripe on the hood so I'm not sure if he knows for sure what he has. The guy says he has to prime it if it sets more than a day or so to get it to started. He says it runs good & will start right up after it has been run for a while. My first thought is the choke is out of adjustment but the guy seems to think that the fuel pump is weak. He is the type of guy that usually doesn't sell something unless something is wrong with it. Anybody have any thought as to what may be wrong with it. Thanks Gerald
