I have a Ronson Jet Lighter my son gave me and when it was new it worked so well I really was sold on it. When I fill this lighter now after the factory fill has run out, it works only mediocre at best.
I have tried emptying it completely and starting over and adjusting the little screw at the bottom of it.

This holds huge sentimental value to me, cause he brought it home one day and said I thought you would like this, so I picked the non shiny one and it’s thin, which told me the kid was listening and he took his own money to buy it for me.

Can anyone help me to get it running reliably again? Thanks a ton in advance.
