Maybe someone out there has a RWS original ignition controller they want to= let go of. No programming required, uses 13-B standard pickup and ignition= coils. Of course you'll have to use carburetor(s).

I have one, but really don't want to let go if it. Its simplicity is nice i= f just want to get 13-B running. (All you have to do is set timing and tune= carburetors.)
