That would have been my guess, ignition is pretty constant (With a few variables) but if it all levels out at 4K and then does not miss a beat I would plump for partially blocked pilots.
Be interesting to know if the stuttering gets worse as the revs climb towards the 4K, before it clears, that would point to partially blocked pilots jets (not necessarily all of them) just one will cause a real power drop not just loosing the 25% but the drag of one lazy pot on the other pots would make it feel more like 50% down.
