The pulse from the pickup coil (senses timing mass on alternator rotor) triggers a thyristor discharging a capacitor through the primary ignition coil winding; the ignition coil steps-up that voltage through its secondary winding, firing the spark plug.
CAPACITIVE (as in, a capacitor) DISCHARGE (as in, discharging a charged capacitor, in this case across the ignition coil primary winding) IGNITION (a spark occurs across the spark plug electrodes, when the ignition coil transforms the voltage from the discharging capacitor to the high voltage required to arc across the spark plug electrodes and ignite the air/fuel mixture in the cylinder); "CDI!"
The use of starting fluid is of no consequence to your electrics.
If you have SPARK, COMPRESSION, and a COMBUSTIBLE MIXTURE, oughta start! The starting fluid insures a combustible mixture.
