Just brought home a 317 for just hauling it away. Sorry I don't have pictures yet. I know, I'm from the last century. But I'm working on it. Serial number is C317J 126096M. After I got it home and started to look it over, it appears to have an Onan B43G engine in it, and looks original. Previous owner couldn't tell me much about it. Yes, I know I should search the archives to find the answer, but it's late and I need to do other things. It does have bar tires, and a newer 48 inch mulching deck. I don't get a lot of time do this, so please forgive me if I don't respond quickly. Thanks guys foe your input. Jim.
