Brilliant choice of gloves in the event of a fire, watching you pull off burning and melting vinyl gloves would have boosted your view count immensely!
The damn O rings on these is only thing I don't like about "Easi-Lite" models. The original valve with graphite packings will last for generations and if it leaks, a turn on the packing nut fixes it in seconds almost always. If it doesn't, it's usually because someone who didn't know what the hell they were doing butchered the machined sealing surface on the stem with pliers. Keep us posted on how those Chinese Viton O-rings hold up over use and time. When these aren't starting right, turn the valve quickly through its full range of motion several times to clean the gas tip and keep the flow going.
excellent stove and a good repair-- the results could have been catastrophic if you hadn't spotted the leak and the valve tray filled with fuel and ignited ! ( would have been hard to turn the valve if engulfed in flames !!!)
