I can't quite be sure I'm reading the colour, or role labels, on the combination switch contact diagram, but it looks to me like the wire coming from the ignition unit is earthed to kill the spark, and open circuit to run. That wire also goes into that multi relay called "combination relay". I'd suspect that relay can kill the spark if all the safety features aren't satisfied. I'd unplug that and spin the engine somehow and it should have spark.
