Thanks for the responses.
I'd be surprised if it's a steeping problem, since the "born on date" is over 4 months ago (12/8/14).
The coil on my new Nautilus is a BVC, but don't know whether it's the small hole, or the newer large hole type with cotton.
I learned the hard way about allowing the wick to saturate on my older Nautilus Mini. Nasty dry hit and burned the wick,
so now I usually wait at least an hour after filling.
