When both cylinders won’t produce a spark, everything checks out OK, but you still get nothing, try this. Mark the center of the magnet in the magnet rotor. On top so you can see it. Rotate the motor till one set of points start to open. Now check to see if the coil that the magnet (your mark) is pointing to – is connected to the points that just opened. If not, at some point, you got the coil wires to the points switched.
