Since this is a simple magneto ignition there are less ground issues than with electronic ignition to check. The connections look clean at the terminal posts and the magneto grounds. Out of habit I always ground the magneto plate to the block with a braided ground wire which is intact.
Granted a sharp blue spark my not indicate the spark is perfect but I have gotten engines to run on a weaker gold colored spark before. My only thoughts at this time are to start at the top down trying to get the engine to run on a cylinder prime and work my way to the carb unless someone has a suggestion for something I may have missed.
It would just seem too coincidental that at the second run when shut down warm a multitude of problems occurred. Since each cylinder has an independent ignition system and it is unlikely a place to look for a single point of failure affecting both cylinders with good compression, blue spark and a decent air/fuel mixture.
