When I take the non return valve out and clean it with petrol the problem goes away.
It seems that unburnt fuel might be getting to it and gumming things up? Normally the non return valve is at a high point in the vacuum line and my valve is low, and close to the servo (the valve was rattling where it used to be). Could this be the issue?
