Hiya folks, this old go kart engine just showed up and I have no idea of it's age or who made it. The tag is badly worn down, all I can see are the numbers 56844 P21, and that it was made in Grafton WI. I know it's not any kind of a wrench, but an engine is a tool of sorts, isn't it? :-) And it's running a Tillotson MD6A carb if that helps.
