I finally narrowed the Nautilus issues to 2 culprits; deffective heads and
vaping style. The first is easily solved, albeit at a cost. The second is to realize that this atomizer demands certain attention.
This
tank doesn't like airy draws; it just doesn't produce vapor nor taste. The best settings are the first and second orifices (from small to large). It doesn't either like to be left overnight on the side with the vents open; it leaks to the base and seeps through the holes. The solution is to move the ring so all the vents are closed, or place it in vertical position in a mod holder.
The 1.8 heads last longer and if you have a decent mod, they can give an equal amount of vapor. It seems to me they give even better flavor and are les prone to clog.
The head must be cleaned regularly. An overnight bath in Everclear or >95° ethil alcohol will loosen the carbon cake. Then, a careful repeated dry burning until you get an even red coil will convert all the crust to ashes. A second vigorous wash in alcohol will remove them from the head. Involved but beats throwing them in the trash can.
When the atty starts gurgling, a pipe cleaner through the chimney and then through the largest vent will remove most of the
juice excess.
The other part of the equation is great tasting vapor that goes on for hours.
