Well, I just changed out the plug. It appears to have been the problem.
It was gapped at 30 (my bad), and I gapped the new one at 35 per the manual.
It was somewhat fouled from oil.
I'm thinking it might have been from the break in, the rings aren't seated yet. It does puff a bit of smoke, but not bad. I guess a little oil goes a long ways, especially when it comes to fouling a plug.
I'm still going to try to find some autolite plugs. What's the number again? 316?
Thanks for the recommendations! I watched the voltage via a light, no change. I checked for a bad connection at the coil or condensor, things were good. I guess I know all the other stuff is good now, I'll just swap in a new plug if it starts doing this again. It sounds a LOT better now!
