Hi there
Firstly I would check the caps. They look distinctly like microwave caps to
me and i dont think that they would be suitible for pulsed discharge. I
would next check the chokes, even remove them. It really is only NSTs that
need such devices - you should really be able to get away with it with an
ignition coil...
