- Dark, oily sludge at bottom outside of carb usually = external fuel leak.
- I think you're on the right track, hotspot-wise. Just need to figure out the cause/cure.
- Since the unintentional ignition during engine run-on isn't timed with the valves, often the engine will run backwards while dieseling, sending exhaust gasses back up through the engine air intake system. Without knowing for sure, I feel safe saying that the acrid fuel/air/exhaust gasses bubbling backwards through the oil bath air filter has a tendency to stink.
That's my theory, anyhow...
