This would flip the mechanical triggering, any possibility of swapping it by 180 degree to test that way  ?

If not, it should run if you swap the coil connections to the wrong way round. It'll have two errors but be corrected to ignite as it should. Not necessarily a solution, but that would prove the error to then understand why that's so.

PennoK3:
Yes, everything fits as it should, all original parts are TEC.

McCabe-Thiele (Ted):
Then might be as Nigel has said your advancer might be 180 deg out.
Have you had the advancer apart?

Did you originally have the left side CB points connected to the blue  wire for cylinders 1 & 4 with the blue wire at the coil end supplying the spark for cylinder1 & 4 plug leads?

PennoK3:
Advancer has not been apart, blue points on the left, yellow points on the right.   Blue coil to 1 and 4 plugs.

McCabe-Thiele (Ted):
I'm not familiar with the DS unit does it need a power supply or is that okay as the red light illuminates.

I've run out of ideas - I assume you have nipped up at least one of the base plates screws to give a good earth.
