Resister value


Tracing the memory when I replaced genuine ignition coil into Lucas gold coil, I felt some change of condition and the discerned the difference of exhaust note.
The difference of 1st stage resister value 3 ohm to 7 ohm must have brought the sensitive and nervous situations and have made it difficult to continue the ignition timing in stable condition.

Knowing that the ignition coil used in the Transistorized system has lower resister value below 1 ohm, this is not favorable for point signal system distributor and the additional resistor to sum up to 3 ohm must be applied in series connection.

But in case of excessive resistor value, no information was found in the Web site. How about connecting parallel connection of additional resistor to sum up 3 ohm?
In case of new parts, Bosch Blue Coil with 3 ohm resister value from the beginning is favorable, so written in the Web information.
