To finbullet and Mick Bailey:
Excellent comments, both of you. Thank you.
I'd just like to say first off that (A) none of the NGKs (many) that I used from May 2014 to June 2017 was in the engine long enough to get "old" to any degree at all. None of them ever "looked right" when pulled no matter how well I figured the carb was dialed in and I would throw another new one in and pray; (B) I experimented with gaps from .020" (Pete Snidal) up to .028" over those years (with the NGKs and the OEM coil) - no apparent difference. I never, ever came close to a cold, first thing in the morning, kick start; (C) when I installed the Pertronix last season I stuck with .028" and still got no cold kick starts with the Pertronix.
I'm going to pull the Champion today both to just look at it (after 18 days) and to check the gap. I'll bet it's around 0.028" give or take.
Now - a bottom line once and for all question:
With the Pertronix and a non-resistor HT wire straight from coil to plug, does it make any damn difference whatsoever To The Engine (I don't care about radios) whether I use a resistor or non-resistor plug?
I don't think radios (car or otherwise) react like the old days to non-resistor ignition systems. Do they? And even so, do I care? No, I do not
