It was quite a thrill to finally get the Frisky Family Three's engine to run yesterday

After spending a few weeks of free time cleaning out the tank, shut off valve and carburetor, and chasing down the spark in the ignition system, I literally couldn't stop clapping over the roar of the engine for about the first 30 seconds after she fired up for the first time in nearly a decade.
The mystery to myself is why I could only get a decent enough spark to get it to run well, if I both disconnected what I believe to be the condensor, (see accompanying picture) and ran a spark plug wire without a static suppressing resistor in the spark plug end cap of the ignition cable from the coil. Put either of these back into the electrical circuit, and the spark would become too weak/ erratic to start the engine.
I am using a new spark plug, and the wires involved look good. I also did a precision job straightening and gapping the points and setting the timing of the point set that is energized for forward running of the engine.
For awhile I used an identical, but slightly shinier example of the same condensor with temporarily good results, but then a short while later, it would only spark well enough to run with the second condensor, and spark plug resistor removed from the circuit again.
John Meadows has verified that it uses a positive ground electrical architecture. However at one point I burnt up a light gauge temporary jump wire from what I believed was the positive pole of the batterry to the 12 volt power in side of the coil terminal. I was trying to factor out the dodgy ignition switch which only maintained power to the coil if I kept some counterclockwise pressure on the ignition key after it started.
It is possible that I hooked the temporary jumper to the negative battery terminal by mistake, as both positive and negative battery cables are in the same red color.
The solder tipped light blue wire in the picture that is connected to the condensor by spring pressure only, attaches to the other minor terminal of the coil, along with the point trigger wire.
Could I have blown the second condensor by grounding the 12 volt power in terminal to the coil just long enough go melt the insulation off the thin gauge jumper wire. No other wires got warm during this brief fiasco.
If it is indeed a condensor, why does it show "500 V max" on both the Scootacar, and Frisky units? Where can I get replacements?
I also have two identical bakelight 90 degree spark plug boots with built in 1 K ohm resistors. She also wont run with either.
