The engine code will give the date of manufacture. Parts and service info for such an old machine will be scarce. Should be fun if you get it going though, you should have good biceps by the end of the season.

Do you have any photos of your tiller that would show how the belts and pulley system is suppose to be? My neighbor has a tiller like this and when I started working on it for him it was all apart. If so please send them to LDM312@hotmail.com. I would appreciate this so much! thanks!
