Throwing my hands up on this ignition!

I can tell from this antic post nothing I can say will change your mind. So I won’t bother. Amps is what does the work. Simple as that. You can argue all you want. In fact, the amp measurement has been so beguiled by MSD even that is hard to deal with. A 20 amp MSD magneto produces the same current as a Mallory 5 amp magneto. It’s the way the current is measured. You can call the guy who owns Fuel Injection Engineering and talk to him. He bought out the Mallory magneto shop. He works on both. Ask him about amps.
How about you ask him if he is considering primary side amps or secondary side amps at the output. There is absolutely NO one that can or will argue the laws of electrical properties, they don't change for anyone or any reason. They work the same in any part of the world or universe. Not even NASA will attempt to go around them.
