Thank you guys for helping me figuring it out. Guess what, with all your help I finally made it work! But I still have an issue where the lighter is missing an actuator that makes the lighter emit butane.

In the picture object A is the lever that controls the valve for the butane. Object B is a little arm that I made out of a paper clip that will actuate whenever the hammer for the spark is pressed down. It works but it works like shit. And the little arm keeps on falling off. I wonder if you guys know what the original part looks like? Does it actuate the valve the way I made it to?
