[Mgs] Bad Fuel Question

Not quite right.  With the points closed the condenser is discharged as it is connected across the points.  When they open it charges up, as the coil is discharging.  The current/voltage characteristic of a condenser (aka capacitor) is 90 degrees out of phase with an inductor i.e. the coil.  This makes it a tuned circuit as in a radio, and an oscillation is set up, which increases the HT amplitude and its duration.   That's why an engine will always run badly without a condenser, and may not even run at all, depending on several other factors.

  Not true, Max.  When the points open, the condenser discharges through the coil in order to perpetuate the spark.  Without the condenser the engine may not even start.  Try it some time. :-)
