I have been using the van faultlessly of late, but last night the inevitable happened.
Pulled out of a junction, and thought the van felt like it had a slight lack of power. Not too much, and so little I questioned myself a bit, but I certainly thought I had to give it a bit `more` to pull off at the same rate as I would normally experience.

Some miles later, approaching a junction, the van stalled.

It started straight away, but had a lot less power than normal - I had to rev a lot more for the van to not stall when I released the clutch.

Anyway, I limped on for a mile or so, only for the issue to suddenly clear. On the `home stretch` it started to return though.

Symptoms at idle now: Slightly lower idle rate, but doesn't stall if left.
Symptoms trying to pull away: Dies immediately if a lot of pedal action isn't applied.! Very similar to if you run an engine cold with no choke.
Symptoms when cruising: Runs smoothly, but as soon as you let off the throttle, it is like you have turned the ignition off and I get a lot if `engine breaking`

The experience of the above changes a bit with severity, but captures a general picture of symptoms.

What do you think?
I have a spare carb I was going to change after the summer - the old one has a faulty choke - but does this sound like a carb issue to the more experienced here?

I initially thought it might be a jet blocked, but the tank, filter, filler neck etc and fuel lines are all `new` after changing this past winter, which suggested to me that there shouldn't be particles in the fuel..?
