    Mystery Motor

    I placed this in the parking lot dicussion but maybe it belongs here.
    Can anyone identify who made this motor? I don’t have a picture but I can tell you the numbers on the casting. They are: H6644 and beside that is another number HCT10. It is an external valve train. By that I mean it has external push rods. It's one cylinder and it looks American. Anyone?
