"Quicker" advance curve; any benefit?
@yellow rose Here's a pic of a plug I just pulled now...

Wow. That plug is actually pretty close. That's damn fine tune up.
If you look at the ground strap, the kinda wide line or mark you see in the middle of the curve is what your initial timing is. Not in degrees, but where it's at on the strap.
If you were down here, where I'm at (pretty close to sea level...I think maybe 800 feet or so...where I grew up I raced at 120 feet or something and the corrected altitude would go less than sea level) Id say you have a bit too much initial. Where I'm at, I'd like to see the mark just up from the curve (towards the center wire) but where you are at, you've nailed it.
The mark you see that's closer to the shell is also pretty close for where you are. At sea level, I'd rather see it up from the shell a bit. But where you live, where the ducks on the pond wear oxygen masks, you've about nailed it.
It looks like you might (maybe...possibly...but I doubt it) be a skosh (and it would be a blonde skosh) hot on heat range. Again, up there where the bird walk rather than fly from lack of air, it looks like you've nailed it.
I can't see WOT but it even looks like you've nailed your idle and cruise tuning.
I must say, I'm impressed. You've pretty much knocked it out of the park and blew the threads out of it on the way out.
BTW, I don't care what the timing light says. You've nailed it. The numbers don't matter to me. Just use those numbers with that timing light.
You should be happy. Most guys don't get their tune up anywhere near that.
