This if from WWW's grandmother, bought flints, wicks and zippo fluid today. Lighters on youtube have a wick. This one has a tiny pipe hole.
small screw appear to be where the lighter fluid goes. Larger screw (opened in the picture) seats a little spring like a retractable ball point pen only smaller.
Finally found some info after looking all evening. It's a butane lighter, so no wick. So, drain the lighter fluid and order a butane cartride
