I blow out any primer than I put a condom from a carto on the bottom of the Atty, I then take whatever flavored liquid I'm going to run in that Atty and I fill the Atty up to the top of the bridge and I than let that Atty sit like that for about an hour. This ensures that my wick gets completely soaked and my Atty's never get that burnt taste, many people just put a couple drops in and fire there Atty, this is risking the wick gets a slight burnt spot on it sometimes and I don't ever get that because its never the same once its burnt, thats my reason for the initial soak to prime it properly, this works every time.!
