No spark.

 I can get a spark from the king lead against the head if I flick the points... but there is nothing at the plugs or end of leads.  The rotor arm is rotating and looks like it is making contact in the centre of the cap. 



I am not sure if a duff condensorl will stop sparks like this? 

As has been stated it looks like a dead short somewhere.??

A duff condensor affects the ability to create a good spark. Various things are possible.

But this sounds like a dead short in the rotor arm. 

Hold the king lead near the head and spin the engine on the starter. You should get a cracking lively spark. Then with the rotor arm in place hold the king lead near the rotor arm and spin the engine. You should get no spark jumping to the rotor arm. If you get a good spark jumping to the rotor arm then there is a dead short within the rotor arm, and it needs a new one.
