Quick question, do the 510 cartos typically come with primer on them and if so have any of y'all ever filled up your carto first ( before burning that junk off )? Again if so what did it taste like? Reason I am asking is I just got out a bottle that I had sitting in my fridge a month or so old, and I filled my carto ( a new one ) and vaped a little bit on it but good golly Ms. Molly I inhaled it a couple of times and it was like I was inhaling Pine Sol or something. I switched to an atty with a cartridge and filled it up with some 555 and everything was well but the other is nasty. Can't figure out if it is because of a new carto or the juice. I can put the juice in the other but the atty is old and almost on its last coil so not sure if I will get the same nastiness. Just curious, thanks.
