OK I know this isnt a vaux but im trying to help a friend and thought someone might be able to help me.
The car in question is a 90 vw polo 1.3 coupe with a pierburg 2e carb.
Initial problem was when it gets warm it cuts out when the revs fall ie stopping at junctions or changing gear, but flat out it absolutely flies.
plugs/leads/cap/rotor arm have already been replaced.
Having discvonnected the auto choke if I close the choke the engine will run fine as soon as you open the choke it cuts out.
So I thought either to much air or to little fuel.
The carb/fuel pump/filter have all been replaced so i felt that eliminated the fuel side!
I have also had the inlet manifold of and resealed it to the head and carb and inspected it for cracks (looking for an air leak!
Anybody any suggestions as it is still the same.
Could I have got another duff carb?
