Expromizer V4 problems

[Kusie]

Hello,
I recently picked up an ExVape Expromizer V4 and I´m having some issues with it.
On paper it´s nearly perfect: MTL only, top airflow, nice easy to coil deck. The taste is very good, BUT:
1. Airflow control ring does not move at all. I managed to open it completely with force but not it seems I can´t move it at all...
2. Airflow is very very tight, even with all holes open. I do only MTL but boy do you have to suck on this...
3. While flavor and vapor production is good I can´t get a satifying thoat hit. Tried to move the coil a bit higher over thw airflow but not much change
4. the most annoying thing: it constantly spits up hot liquid up the mouthpiece... Tried different wicking methods and materials (cotton, rayon) but not much has changed. I´m MTL vaping a 1 Ohm Kanthal coil with 9 watts....

Any tipps from owners of this tank are appreciated.

Wow, nobody? This forum seems almost dead, did everyone move on to another forum or stop vaping?
Just curious, I´m fine with noone answering to my problem.

Likely no one still has the tank since it's 3 years old?

Hi Mate,
Which devices had been building/using before the V4?

A photo of the build is going to go far in getting to the bottom of the issue.

But until then:
What is the ID of your coil?
How many wraps?
How high is the coil above the air flow?
Have you removed the air adjustment ring and lubricated the o rings on the tank? Re-placed with new spares?
Is the draw resistance the same with the tank clean/empty and coil-less as it is "ready for battle"?
What is the nicotine level of the juice you are using? The VG/PG ratio?
Which battery device are you using and in which mode?

Cheers
