automatic choke/throttle/start up issues
Hi, Just wondering if anyone can please help with a problem that is giving our mechanic headaches?...... My van is currently at a garage and has a problem where there is a delay when you press on the throttle. Once she has been running a while, she is fine, but is a bit tricky on start up and cuts out several times at first. She's had a service - new plugs, oil etc etc, but is still not a happy Wedgie van Has anyone had a similar problem, and if so, what was the cause and how did you fix it? Any help greatly appreciated. Thanks! Diane.

Re: automatic choke/throttle/start up issues
Whilst I do not like helping supposed qualified mechanics ... 
It reads like the choke pull down unit is at fault.
Or the choke is not functioning, presuming you follow the start up proceedure.

Re: automatic choke/throttle/start up issues
Hi Kev, thanks for replying and for your suggestions.
The guy has been a mechanic for many, many years and has his own business. He does great bodywork repairs and also mechanics as well. He's worked on my Renault and is a good, honest guy, but he isn't a VW specialist. He's only had a handful of T25's in over the years. If he can't sort her out, I will have to find a specialist garage to check her out. I know these vans are a bit quirky, but as he is sorting her surface rust out, I just asked him if he could do the service and generally have a look at her mechanically as well.
Thanks again, I will tell him what you suggested.

Re: automatic choke/throttle/start up issues
Carburettors are not rocket science, they have been fitted to cars since the 1800's
The pierburg 2e3 is the last of the line really, injected engines soon followed.
Following your description of the problem, it was clear to me that the issue is during engine warm up, thereafter it runs good.
So that tells me it must be mixture.
Cold engines like a rich mixture during warm up, it takes about 6-8 mins to come off the choke (flap open fully)
It's really the only time where the mixture is richened.
Without the richer fuel to air mixture the engine stalls under quick accelerator depressing, coughs and splutters. because the throttle butterfly is opened demanding great gulps of air, and cold engines like more fuel than air, so it misfires.

Re: automatic choke/throttle/start up issues
Really appreciate your help. We are taking her to a VW specialist tomorrow. Got her home tonight and have had no end of trouble with the alarm/immobiliser going off! Just teething troubles I guess. I'm sure we will get her right soon.
Thanks again for your advice Kev.
