just picked this up today from my dad's. it is a vintage fox mini bike. the motor is not original, it has a briggs 3.5hp on it. pretty sure these came with tecumseh engines. gonna fix her up and ride it! shoud be fun, and should be pretty quick to do also. just not a whole lot there! :wink: anyone have any more info on these and any idea on what year this might be from i would like to know. thanks.
