sorry if it`s a daft question but i car`nt figure it our, the lid on my old burner broke so i brought a new trangia meths burner, on the lid is a seperate lid that comes off and has a piece that pivots round, i presume the top with the pivot closed is to put the flame out but why does it open out, PLEASE help i`m using it tomorrow
cheers
