I think I only have one AGM lantern with the hidden valve behind the tight fitting, 180 degrees from the main valve stem that functions as designed. A few I have had to plug the tiny fitting that is next to the fuel pickup. The weak spot I think is that little valve opposite the main valve shaft, it is a metal to metal fit. My recent Kamplite catch starts dimming a little after 20 minutes, but keeps on running for a few hours more. Anyone had success in clearing that start circuit, especially finding what the issue was? I tore this one down yesterday and soaked the valve in hot vinegar for half and hour. I checked for fuel spray and stream when I put the valve back in the fount, hopeful that I cleared everything, looked great, but same results as before. Duane
