So have you changed the cap n tried a different set of leads.
The phase sensor would stop the KING lead sparking all together.
I.e if your turning over the engine with the lead off and its sparking= That means that the phase sensor has no problems.
It could be in the wrong position regarding the TDC settings of the Dizzy tho.
If you are getting a spark to the king lead, then connect it to the cap with a rotor arm inside. REMOVE PLUGS, Then crank engine while the leads and plugs are resting against the rocker cover. It should spark.
If not:-
CAP
ROTOR ARM
LEADS
PLUGS
one of the above are faulty.
CHeck the above and let us know
