Supposedly you can test then with an ohm meter.
You would set the meter on the 20k setting, a new plug would read around 1000 to 8000 ohms.
That's a wide range, but the high voltage should have no trouble making the jump.
To test, put one lead on the top terminal, reach in and touch the center electrode tip only with the other lead. That should give the 1000-8000 reading. Then set the meter to a low setting or continuity setting. Check from the top terminal to the base. Should get open, no conductivity.
Interesting theory on resistor plugs. I always though it was only for radio noise, but there is another reason. It gives a hotter, more definite spark. Check out the 5th topic about low resistance. I realize this is about aircraft shielded plugs, but still the same theory.

It wasn't to show off my restoration skills (though I had tried my hand at a couple of old motorcycles in my teens and if I recall correctly, those old motorcycles were sold in boxes about one quarter finished). It wasn't to relive memories of Grampa, Dad or myself out on the back 40 nursing the Farmall pulling too many b
