I've had the same "problem", but I think it's a good thing. It's either that the carb-bowl's fuel is aerated from sloshing (doubtful), or there's not enough fuel getting in at high-revs (probable). Hold down the tickler with your left-hand when it starts happening again and report your findings. Better yet...for safety purposes...bring along a small child for the ride and have them do it.
