If your'e not happy with the connections, neither am I. It goes without saying the all need to be clean and sound, as in no oily wires twisted together.
More things to check
Check the resistance values of your magneto source coil = 420 ohms +- 10%............Brown to chassis
Check the resistance of the magneto pulse coil = 12.4 ohms +- 10%...........White / Red to chassis
Check the resistance values of the ignition coil, Primary = 1.0 ohm =- 15%, secondary = 5900 ohms +- 20%
But sort the wiring first.
