Here is a suggestion I was given to help further with my cars lil problem!! :-
'What I suggest you do is visit the Classic Panda section and ask the members there if there are any additional vacuum pipes connected to both carburettor and transmission. Though the Panda Selecta uses a different engine the Selecta transmission is pretty much the same. Unfortunately the carburettors are different between the Panda and Uno.'
I would appreciate anyones help? Thank you kindly, elise x
