Hello, the adjuster on my lantern is inside where the knob screw is,but you seemed to have worked out the problem..enjoy

I had a Northstar lantern sitting on top of a propane tree a few years ago. I lit it and the whole thing burst into out of control flames, melting the plastic to the point that it was ruined. Good thing I had my fire extinguisher was within arms reach

It's nice to see someone using an old school lantern.I'm sick of seeing led technology even if it is better
