Hi all! I just got a great running speeditwin 28 hp. Right now i am using the pull rope to start it because it has not ignition switch or keys, but the wires are all there. I want to hook up the wiring for electric start, but cannot figure out what wires are what. Also, if don't use the wiring and use the pull rope to start it, how do i kill the engine? Can i hook up a kill switch some how and where do that? its a model 28303.
