All engines that use a 12 volt system and point ignition use a resistor in the current supply to the coil. Some use a wire in the harness some use the ceramic and some use a coil with one built in. John T explains it perfectly a couple posts up. Points open and close thousands of times a minute. With the higher pressure or amps of 12 volts they will erode or burn themselves up rapidly. That's why the resistor is used to cut the current and greatly extend the life of the points. To sum it up if you have a 6 volt system no resistor is needed, if you have a 12 volt system a resistor is required in some form or points will have a short life. 6 or 12 volts has no effect on the condenser so don't let that confuse you more.
