So lately on running into issues with almost all of my lights from ronson to vertigo to lotus to soft flame. When empty I purge completely turn flame to low and obey to fill. Wait a few seconds full again and let sit ten minutes. Warm hands and proceed to light. Sputter at best. Fill again let sit light.sputter again. Wth. I didn't used to have this problem. We need a sticky on lighters..... If there isn't already one.
