As long as your ignition system has enough energy & voltage to jump the gap with an adequate spark. Making the spark "bigger" adds no more HP.
A high rpm, high compression or exotic fuel engine takes more energy to jump that plug gap. So the "Blitzburg" ignition systems are required to ensure an adequate spark.
Taking your JD B and adding a straight pipe, the carb off an A or G, high octane gasoline and a high output ignition system. Will not increase that B's HP up to G's HP. It might make the stock Nebraska number for a “B”.
The advantage of electronic system is no point contacts to get corroded or worn. The sudden stoppage of current to the coil will throw a stronger spark than a points system where current gradually drops as the points arc open.
1.5 ohm for 6V, 3.0 ohm for 12V without bypass starting which means no ballast resistor. And 1.5 ohm with a ballast resistor on a 12V machine with bypass starting.
I have to run my writing through the spell checker to catch most of the errors. We should keep track this year how many times somebody asks about “hydrolics”
