just recently had my 56 beetle wizard tuned,had weber carbs balanced,upgraded jets,mixture all spot on,running perfect on rollers,when i went to drive her home...coffed spluttered and cut out on ,me when having to stop\slow right down. took it back,he said i'd prob need new coil and condenser(which wasnt right fitment anyway). I think she seems like shes overheating.......any advice...thorts ????????
