Like Rusty noted resistive suppressor (some are carbon core instead of wire) wires n plugs came into the picture (among some other reasons) partly to reduce RFI noise to keep the radio quieter. The thing is the coils HV secondary output of a relatively low energy Magneto matches up much better if theres little resistance/impedance in the plugs and plug wire circuit (NOT counting for the open gap), so regular non resistor plugs (what was used when mags were developed) are preferred. While that issue is less relevant in a batetry powered coil distrubutor ignition I figure one may as well use a non resistor (3116) plug there also. While its not much, Id just as soon discharge all the avaialble stored energy the coil has to offer by discharging it across the plugs gap (volts x amps x time) versus as I squared R heat loss in resistor wire or resistor plugs. This is similar to my preference of bigger then stock battery cables on 6 volt tractors, say 0 or 00 versus No 1 or 2, Id again (regardless if not all that much difference) just as soon discharge it in the starter then I squared R heat loss and voltage drop in the cables, since when its extremely cold, the starter may draw twice the normal current (say 300 amps instead of 150), battery voltage may drop to 4.5 instead of 6.3, and ALSO battery efficiencty is greatly reduced at cold temps.
But Hey Im just wired that way and am conservative and yes I MIGHT over build and over design now n then, its just how I was raised n trained. I doubt the performance would be much (if any) different if you used 386 instead of 3116 and unless its extremelyyyyyyyyy cold your old girl would probaly still start heck even if you used 4 gauge cables lol

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
