Friend gave me a 1966 MS 50 Puch with a complete engine. I know very little but wondered if anyone knew more. Does the ignition run primarily off of the magneeto? If so, there are three other wires comming from the same area on the engine block. Curious as to know what they are like. How many speeds? Supposedly automatic? What kind of engine performance should I expect if I get it running? Please help if you can.
