    All of a sudden my 1977 t140v starts running rough when I turn on the headlight. If I don’t keep up the revs it stops. It like it’s being robbed of power. Any thoughts?

    Start with testing the battery and then the charging system just to make sure that something is robbing the power rather than there being no power there to start with. Then it's an elimination game as there's a bad connection somewhere earthing. I'd begin with the headlight :)

    I’m thinking it’s the headlight wiring too.
    Tks for your help
