givenchy lighter not working
good day! i recently got this lighter (givenchy 9000) from a thrift store. i took it home and changed the flint, purged and cleared out the tank. but when i tested it, darn thing wont light up. i can hear the "pss" sound it makes when i open the lid and im sure the tank works fine because i took it apart and tested it (refer to the 3rd photo). i even tested it for leaks but oddly enough, there seems to be none; from the joint, or thumb striker part.
one more thing, when i took it apart, i kinda forgot where the u-shaped clip belongs when assembling it (refer to the 2nd picture) so any tips on where it actually belongs will really help.
asking for help regarding these:) because i pretty much went through everything i can find online but nothing pops up. anything helps, thank you! :D
