OK, sounds like you did a spark check by cranking the engine at several throttle settings, am I correct?
If so, I would definitely use one of the little inline neon spark testers to confirm/deny spark issues while it is running.
The other engine does the exact same thing, even with a prop installed? Seems like a strange coincidence….Have you checked to see if the carb butterlies move freely? The throttle shafts might be sticky/binding keeping the throttle plate from closing properly at lower speeds, this is pretty common on these little engines.
