I have a SDII from TW that I have been using with 510 cartos and an adaptor and decided to try some 898 cartos so I don't have to use the adaptor. I got a box of smok Teck 808 carto in the mail yesterday and got ready for a new expriance, filled one with juice, put it on, and I couldent draw through it. I had read that 808's ware the same as 901's but apparantly the air passages are different on my unit because when the 808 is screwed on my SD I can't get any airflow through it. 
If there some way I can fix this w/o using an adaptor? Does anyone make, sell 901 cartos or 808 cartos that will work on the SDII?
