About the same time engine compression was increasing. The increase in compression lead to more of a voltage drop when cranking the engine over. That voltage drop caused the volt to the coil to drop and in turn the coil putout became weak and the engine was harder to start. To compensate for this the manufactures bypassed the resistor while the starter was cranking so the voltage at the coil was enough to provide strong spark.
So, by using a 12V coil, you lose the advantage of ignition system bypass wire compensating for voltage drop during start.
