I figure with all the northerners in here a few of you ought to be good with salamanders. Mine will only work with the lid off for a minute or so. Will not light with the lid on at all. Used to work perfect then one day decided to be a POS. I tried a couple different pump pressures thinking maybe my elevation was a factor but that had zero impact. I disassembled the nozzle and blew carb cleaner through it, but it was clear. I blew through the pump line and fuel line, both were clear. Cleaned the already clean optical sensor, watched the ignitor glow red prior to ignition with the lid off. Everything looks to be in order but it just won't light with the lid on.
