Thanks so much for all the input. Really appreciated. Good tale there mark T. If only my bike would start and be secretly ridden!
Unable to do anything tonight due to family commitments and Manchester utd being on tv….

But I have made a nice list of things to check and do when I get in there. Maybe not quite time to get the petrol can and matches yet!

On inspection of the stator it’s had work that isn’t great and may need serious work. The wire from the points to the source coil/condenser looks too short and is very close to the crank/flywheel cam area. Could do with re-routing and lengthening. On the same area the points wire/source coil wire and output to ignition coil are not soldered to the condenser but all soldered together with a separate wire joining that soldered group of wires to the condenser. Isn’t right but I am told that electrically it should make no difference. It’s not right though and I should probably sort that out. I don’t know if it’s ok or not.

New connectors and some cable/wire on order.

I will let you know how it all goes but interested in other peoples more educated view on the condenser wiring.

I have tried to see a spark in the dark but no joy and I am not brave enough to stick my finger in the plug cap!

Thanks again one and all..

Ian.

In an early post you say red wire into the coil. I'm assuming the coil has only one wire in & not a two wire battery ignition coil? as red is a little unusual but if the only way in then all good. Coil secured tightly to the frame. Engine mount bolts tight from an all over earthing point of view.
