    Default I'm trying to get an old S

    I'm trying to get an old Sears motor running for a friend. I was wondering if someone could tell me the right fuel/oil mix ratio. It's a water cooled motor- I'm guessing manufactured in 1960 by the chassis number.

    Chassis # 217-58560
    Serial # 203272

    "My buddy said last time he had it running he mixed 50/1 and he said it seemed like it was running too rich??? (very smokey and sputtering) There's now way it should be any leaner than 50/1, right? Thanks for your help."
