The insulation on the wiring from the stator had become brittle with age and crumbled away from the green and white wires where they go through the hole in the back of the plate. I guess that it had been hanging on but had finally fallen off after I disturbed the loom when I did the DC conversion.

The bad news is that I've now got to rewire the whole thing. Still at least that's only time rather than money.
All part of the fun ;)

I spoke too soon. Its still missing. Next likely suspect is the Agusto. I thought I'd tried that though. I'll reset the timing from scratch.

Ditched the Agusto, retimed it and now its running fine. I guess something has gone wrong inside the magic box.

So is this the first Agusto to go wrong or is this where we find the failures coming out of the woodwork?
When was this one bought, and anyone heard of any other failures?

I had a perfectly running lambretta using static timing and normal AC electronic,
fitted the agusto,everything was fine.

After doing the DC conversion with the Agusto,the Ducati CDI went bang in two weeks.
Changed the CDI (Ducati again) and tested the Agusto with a strobe gun and it was working as it should be.
Now I'm back to static,17 degrees.

I don't know if it is coincidence,i.e. if the blue CDI was going to fail anyway,
but I'm not going to use the Agusto with the modified BGM DC stator.

Theoretically the ignition and lighting circuits are separate and so it shouldn't make any difference. It did make me suspicious though. The scoot had been running fine for the last two seasons.
