Not sure how easy this looks to get at - when it's stone cold it chugs badly for the first minute or so then is fine. I have to hold the revs up or left foot brake until it smooths out.
I can live with it but thanks for any help.
Sounds like it could be simply that the carb needs setting up, If the car runs fine once its a bit warm. Theres a myriad of different bits to adjust. Often age non educated owners and the MOT centre adjusting mix etc can throw them out.
Rubjonny the God of all things VW made a guide. It should be on the forum. Its easy to follow and will get most peirburg carbs to behave. Worst case you’ll need a Waxstat or pull down unit. Ive fixed several that were supposedly borked but just needed correct setting up.
Thanks that does look useful.
