Reading all this again, I’ll bet you were dinking around with the throttle while running in neutral, which initiated the runaway.
It also seems to confirm that the timing or carb synchronization is off. The carburetor throttle shaft should remain almost closed until the spark advance is at the full advance stop. Too much carb opening before full spark advance is reached will make it bog—big time.
