My grandfather just gave me a Eatons Viking 3.5 hp motor, he doesnt remember what year it is and I am curious to what its worth, IE are these decent motors or gonna be tinkering all the time. It has minor garage scuffing, but overall very nice clean condition. I found a pic of one like it but mine is in way better shape, Im sure it will go with some fuel but dont know the ratio either . any help would be apprieciated. Thanks in advance
