yeah, I have tried that many times. when I had NOTHING better to do, I would lie on the floor and try to see in there so I could get a mental image of where it needs to go..then spent much time trying to find it by braille.
I managed to get it on a whim..but it only lasted a couple of turn ons.
Since I won't be having to ignite it often..I sit in one spot for months on end, I can live with manually lighting
it. Seems faster and more fail proof thanthe sparker method.
