Lister D - First Initial Run - After Rebuild

Lister DK now completely rebuilt / restored and ready for its initial first start up and run. Third video in the series.
Sadly for me, it didn't go too well, as you can see by this film.
The timing has been checked and double checked, Points gap, Spark Plug, Petrol, Tappets, Carb, Float, etc etc... all appears ok.
My Gut feeling tells me Im getting an intermittent spark. After many hours of checking my work, Im convinced my faulty running D is in the electrical side of things. I know I have a cracked Points cover, electricity could be tracking?and I have witnessed lots of sparks from the contact breaker points, from memory this is not good as I recall, Possible condenser fault?
Head scratching time now...
