I keep only getting 5-10ml out of my cartos then the draw gets so tight I can barely draw thru the carto. I think my center posts are sliding in and blocking the airflow! I can see thru my carto, and the little holes about the threads are clear...but still get a hard draw. I understand they are disposable...but 5ml and throw away....thats a bit expensive.
Do you all think my center posts are being pushed in? I have seen folks say the move them out/ twist them.... how do you do this. I have tried but to no avail.
Thanks all.
