Hi Chaps,
I am building a half scale hit & miss stationary engine (a Sparta/Jaeger/Hercules Economy) and have got to the point where I need to start thinking about ignition systems.
For the stationary engine boys out there; the design calls for a Webster Tri-polar dummy magneto with a spark plug fed from some of the available electronic systems which is not right as the Webster's were typically low voltage magnetos and only used with an ignitor.
These engines were originally supplied in a number of guises including, battery + ignitor, Webster tri-polar and ignitor or Wico EK and spark plug (amongst one or two other options). My thoughts are to build a dummy Wico EK containing the necessary electronic wizardry for a spark plug, or to use a battery and ignitor in the interests of building something as true to original as realistically possible.
My question is: has anyone had any success building a small (half) scale ignitor to use in place of a spark plug? It's easy enough to build the device but I'm not sure about its potential performance on a relatively small scale engine.
I know Bob Shores in the States has a book on building a half-scale Wico EK which may be an interesting option but I thought I would explore the ignitor idea first.
Any ideas?
Regards
Mark
