I have a Colibri that has been floating around my shop for about six years now and still works fine...when I can find it, it's hiding out right now :laugh: .
Anyway, you can try all the tricks you like, mine has never been bled before filling, or chilled unless the shop got cold, and has always been filled with Ronson fuel. The one thing I do when the lighter starts acting funny is to blow out the jet with compressed air and that makes work like new. I have never herd a good word about Colibri so I will not buy another but this one doesn't owe me anything.
Of course now that I am a member here, I have become much more refined and fill my Lotus (can't find it either :angry: ) and my two Xikars with triple filtered quality fuel, and if the lighter is low enough I sometimes purge the remaining gas from them as well, but not usually. The compressed air trick is the ticket for cleaning up the jets which can be affected by fine grit or lint from your pocket.
Until I started reading the cigar boards I have never herd that there was a careful process to filling a lighter, and I honestly really do not sweat it much, I do buy good fuel and that's about it. Over the years the only problems I have ever had were fouled jets, or broken parts from dropping the lighters.
see ya
