John
You mentioned that the kill switch contacts were loose in the plastic insulation, could you be getting intermittent contact there causing your misfire.?
Years ago I had an occasional misfire on my T120 and that turned out to dirty contacts on the ign switch. That was only a straight on/off so easier to open up and clean.

Good point Chris that I dismissed. The round contacts were just able to rotate in the insulation. Not exactly free to rotate easily. I cleaned up the contact faces and the slider but really nothing to clean that indicated any arcing across the contacts. As the problem seems to affect lights and ignition I believe it has to be somewhere common to both circuits?

I may not be able to strip out the key switch which I have in the old electrical box which is a worry so only way may be to replace it. That and the regulator are the only items that I cannot strip to find something that could be intermittently earthing out.

Could well be ign switch contacts as power for both ign and lights pass through it. Not necessarily earthing out, possibly high resistance.
Another thing, you dont have a key ring/fob in your ign key? As that flapping about in the wind can give the switch a hard time and cause early failure.

Oh yes, now you mention it, I've had that.

Yes, I do have a small key ring/fob on the key. Possibility over time it has loosened off the main switch contacts :?: Could it be that simple :?: Arrrrrgh :!:

I did a club run up into the mountains today 180 kms within the Namadji National Park and not a problem :grin: . Replaced the ignition switch with a simple keyed on/off marine variety and checked wires again. I can remove the key on or off so no weight on the internals.

Such a lot of heartache :???: .

GM just recalled thousands of cars because of people hanging too much weight off their key rings and I don't remember what side effect that had other than switch failure, fires?, something.

And I thought I had a problem :shock: :!:

What really threw me was the Pazon was still operating on very little voltage as supply earthed out. But it certainly didn't rev too much and ran rather retarded.
