I used that Iroda in the pictures in first post. Don't worry too much about having to connect a piece of the wire from the original unit. Just trim the insulating sleeve a bit and slip alongside the other one under the sleeve. No metal to jump to but a small piece of electrical tape not a bad idea. And I trimmed it somewhat to be able to slip it into the chamber bushing easier. Also, make sure you have good contact between that "U" metal spring type conductor between the gas inlet valve and the bottom brass cap of the igniter. If not igniting close to 100% you can play with the placement/length of the wire going into the chamber. A very small change can make a huge difference.I went out last night and bought a torch lighter. Took that thing apart and found out the wire is too short, only about an inch long. I tried putting the original one and that one together, but it was really hard to fadangle the wire around and keep it together, especially with my limited supplies. (tried electrical tape to hold the peices together)
I got a spark on occasion but the wire wasn't properly set in and secure. what kind of lighter did you use to replace it? Maybe I'll have to get another brand or something that includes a longer wire
Good Luck,
