So I bought a can of Colibri butane to refill the Firebird I just got off eBay and it just doesnt work? Like the instructions said, I pressed the little pin to let the gas out of the chamber, set my little control knob close to 'L', and pressed firmly on the can for 4-5 seconds while the lighter is upside down. And yet, I feel that nothing is coming out of the can. I repeated everything a good 10 times and after letting the lighter warm up (it didn't get cold in the first place, no butane got in), all I see is the little spark. Any help?
