Re: explain this igniton
this late 40's 3.3 evinrude took it apart and cleaned the points, Must not have them back together right as they short to ground, but that is not my question. The question is there is a kill switch on it that when in very low speed is activated and grounds the points killing the motor. But both sets of points are tied to it.
I'm not sure about your particular model, but my Zephyr has a couple little tabs, under the timer handle to ground out the points. I have seen on some older engines that there is no grounding switch at all, just simply move the timer lever all the way to the left.
Unless both sets of these points open at the same time then if they are tied together then they will always be grounded out? If they are opening at the same time then that means both cylinders fire at the same time?
I would imagine that your motor would be an alternate firing twin. As I recall, Johnson started the alternate firing twins somewhere about 1930 the opposed twins typically fire at the same time and the opposed fours will have two cylinders fire at the same time then the other two. Typically, twins that have one cylinder over the other, will be alternate firing. A good way to tell this, is if there are two coils, verus one.
My other issue is finding the right diameter plug wires for it. They take a smaller diameter wire and the standard ones may not work as you have to coil the wires under the mag plate to allow the plate to turn freely.
There's a good possibility that you can find replacement spark plug lead through Engine Blade and Prop Here is their address and phone number:

I hope this helps.
