The sudden shots of vacuum hitting the jets as the throttle is opened quickly can often clear a jet blockage but you need fairly high revs and hence vacuum to do it.
For now I'd pursue the condensation idea as that seems the most likely.

Although the valve seems to be operating OK now, I think I had problems with it many years ago.
I also thought of a blocked jet, already tried your suggestion.
Never taken a jet out of a Webber before. Hope I don't have to.
As you say, I'll pursue the condensation thing. Not had my travel out in the car today.
