The squirt of carb cleaner getting the revs to rise sounds as though we're back to fuel starvation as the most likely cause of the problem. At least it's not the ignitor restricting the revs.
You must know your way around the carbs better than me by now so I'm reluctant to suggest silly things like carb slides jamming or the throttle control not able to turn the butterflies the full 90ยบ. But, on the other hand, I can't think of anything else at the moment, sorry.
