Unit is built and spun up on a machine to adjust and place some initial wear on the contact points and lubed. I install a new NAPA cap and rotor and check for hitting , if it strikes i just belt sand the rotor a little bit.
I have tested these using a lab scope checking for rotor cap secondary voltage. A good coil will give you approx 20,000 volts , a good idling flathead will use approx 5,000 volts, opening up the rotor gap may use a couple hundred more volts, not noticed when you have 15000 reserve volts...even hard to see the increase on the scope..
Actually in the old days we used to open the coil wire gap to start a flooded engine and the snake oil folks sold a gap for every wire at the state fairs etc to make the engine run better ......   |
A bit off topic, but I loved watching the "Spark Booster" gadget salesmen at the fair. They would take a rough idling car and pop the booster in or out so quick that the engine would not die. The idle magically smoothed out with the gadget in place. Tuning the demo car to do that must have been fun.
