Stiff draw on Nautilus on largest airhole!

[Ryan Lee]

Hey all, first post for me! I dropped a new bvc head in my nautilus after a good cleaning from sitting for awhile. Problem is, the draw on the largest airhole is not much looser than that of the smallest. I have cleaned, rinsed, and blown out all particulates with compressed air inside the airflow control. But to no avail, it is still very tight. Anybody else have this problem, or better yet maybe a solution? Also, if I let it set for a couple minutes, upon the first fire it always spits a hot juice wad into my mouth. Maybe just a bad head?

I've never had that happen to me but the draw goes through the center positive pin of the head. Maybe wiggle it or spin it with pliers to loosen it, or put a pin in from a head you know worked. Just watch that wire that you don't push it up into the coil. You may have gotten a bad head or someone misrepresented a clone made badly.

That pin just pulls out and one of the coil leads just sits beside it inside the insulator. it might be jammed. It won't hurt it to pull it out gently and put it back in. If it's not that, then there's something like wick material or something blocking airflow. pulling that pin you should be able to see all the way through the coilhead down the center.

If it is not flooding, sounds like a defective build. Something may have folded or was misaligned on assembly.
BVC heads are fairly open straight through the center when correct. All the air flow magic is controlled from the bass.

I'd swap it out, wipe it down and do a good inspection.

Well I am a little late with the response. I just wanted to thank you guys for the feedback / ideas. I took the head out and played around with the gasket a little, and gave it a good wash. Seems to be a bit better now, but still too tight for my liking. I tried it without the head in but still sealed up, and it was even tight headless. So that tell me it is the base that is giving me the problem. I guess I was just hoping for a looser draw than what these things can dish. If I seal my lips around the drip tip and let out all my air, i can easily go 20 seconds on a draw from the lungs on the widest setting. Only thing that seems to help a bit is to leave a gap around the tip when inhaling to incorporate some outside air, but then flavor diminishes a bit. I guess I will just have to stick to my drippers and mechs for now until they come out with a more "airy" tank. Or I could just bite the bullet and get an rba, which I would prefer over some prebuilt head anyway as I have a lot of experience with building coils. But thank you all again.

Try using an airflow control drip tip. I use one on my Kayfun as it has a tight draw.

Great idea, I like the way you think!

Ryan - I am new to the forum as well. I know I'm a little late but figured you may be able to benefit from my findings. I had the same problem. I broke down the tank and removed and cleaned out the coil's bottom pin. Then I took a sewing needle and pushed the wicking material away from the airflow path on both the top and bottom sides. I then reassembled the tank.

Using these steps I've gotten 100% improved airflow!

I was very close to writing this tank off until I did this. The airflow was CRAZY tight. Vapor was still good but I really had to work for it. Now I'm pleased to say that this tank is living up to all the hype and will be my daily driver.

Awesome advice! I was needing something small and easy to stick on my little 20 watt eLeaf iStick device, and as thinking about getting my Nautilus' little brother, the mini. Now I will have to give this a try, and hope for the best. Thank you so much, I think you may be on to something.

I also like an airy vape, and the best clearomizer I've found for that is the Anyvape Davide. The newer version is sold as a bdc, but can be changed to single coil by removing an adapter ring. It does not come with an adjustable airflow, but it doesn't need it. I regret that for my vapeversary I decided to get a Nautilus instead of another Davide.

I recently acquired a big Nautilus, and two minis. They work great. Best tanks I've ever had. They are a bit of a complicated design, compared to say an iclear 30, or a ProTank. For that reason, we may encounter different problems than we're used to. It's easy for me to say this, since I haven't had the problems you guys are experiencing, but so far I'm lovin mine, and hope that if I do have problems, I can fix them. I will certainly try, and not give up on them if at all possible.

best regards, larry mac

The mini is great.

 

[Ryan Lee]

I agree, the mini is superior to the original nautilus. Something about it having a smaller chamber really concentrates the flavor even more. And them bvc heads are by far the best mass marketed coil to date. I rarely use a tank as I have a collection of mechanicals and drippers, and you can't beat the flavor these put out with a good build. But, if I am out and about, the mini nautilus on my 20 watt iStick by eLeaf is a very satisfactory vape! Enjoy them lvm111, they are relatively hassle free!

I have the 5ml nautilus and have always found a difference between say the smallest and largest holes.
I read vg is thicker so if your using a higher vg liquid that may have something to do with it.
Or probably for some reason not wicking/firing properly.
