Many, many thanks for all the suggestions. This small issue of no spark is
shaking my belief in the Spitfire gods. Earlier today, thinking that it
might be cleaner just to put in the electronic ignition set because it
included a dizzy as well as the magic box, I tried to install it.
Ahem, the flat bar in the bottom of the shaft, that engages into the offset
slot in the drive gear, would not engage. It is 180 degrees out. (Rotor
points at 4 rather than 10 o'clock). Comparing the 25D dizzy I was using
before, to this one, they are indeed reversed. This is, another, un-expected
eventuality. (Wry smile).
Using the electronic set-up, I turned the engine over with the plug wires in
the normal position, and then changed them around so that #1 was at 4
o'clock and so forth. No change.
There is no ballast resistor in the circuit at present. Tomorrow I'll remedy
that, and use the suggestions to do more testing.
It's not a good thing, but having lost my job 3 weeks ago, means I should
have time to chase down this problem, eventually, with help from fellow
listers and club members.
Thanks! I'll advise of progress.
