I took my Nautilus 2 to a local shop after I've been experiencing some clogging issues. They stripped it down, washed it with lukewarm water, put a fresh 1.8 in, and it pulled like it did when I first got it. Since then, it'll still get clogged up pretty easily, even after I wash and dry everything and put a fresh atomizer in. I'm wondering what I can do to bring it back up to prime conditions. On a 1.8, I run it at 10W and use a 60PG/40VG. I take care not to overfill it and have the airflow ring closed when I do refill it. Even with the airflow ring opened up all the way, it still pulls like I have 1.5 open.
