It runs nice down low, there are no issues until 12k rpm onwards. It's very strange, I would've thought the worn emulsion tubes would've screwed up the midrange more and not so much the top end. I guess the proportion of the total fueling from the needles is quite high, otherwise it wouldn't be an issue.
I guess that's the interesting thing about carbs, fuel is supplied through all these different paths in different proportions throughout the rev range to maintain the right air-fuel ratios. And its all mechanical, amazing really.
