    Actually electrical ignition systems were not used on early gas engines…they had something called the hot bulb also there were a type of semi diesel engine that required use of a blow torch to preheat a spike or plug that stuck into combustion chamber. Needless to say magneto
    or Delco system or modern solid state ignition are superior in many respects but once upon a
    time engines did not have spark plugs or electrical systems. There were also electrical ignition systems with points inside cylinder. As weird as some early ignition alternative were they all
    worked well enough to sell and satisfy customer until something better came along.
    Remember the cars that would run on a few decades back when Detroit was trying to clean
    up emissions and increase fuel economy? You had to leave it in gear when turning off the key
    to get them to stop.
