Spark Plug Advice Needed

Your fine. No worries here.
My bad. I'll shut it down on my end then. Don't forget about the pump shot on that carburetor. Lots of times, when you lean one out it will get a stumble off idle, because it may need more pump shot so keep that in mind.
The Edelbrock rods will be here tomorrow and I can get a better read on a hotter plug.
