Hello Friends of Manuals, not long ago that I acquired a Golf A2 Model 87 and I am trying to repair myself now I have doubts about the carburement I have about 3 months leading it and it has not failed me but sometimes when he is heating I notice a bit of black smoke when I am accelerated automatically and according The semama is around 6 km per day for 6 days I feel the engine strongly but I don't know if they can give me advice on how to adjust it better in advance, 问候。
