Aspire cleito spitting

Hi all.


I've just recently bought 2 aspire cleito tanks and I seem to be having a problem with then spitting. I've searched through threads on here and tried the suggested methods to stop it like shaking out the tank and longer drip tips and I've had no luck.

Only thing I haven't tried is swapping out the standard coil that comes in the tanks with the stainless steel coils.

Any help would be muchly appreciated.
