Vespa 50n 1971er actually has a rotary pusher? Or? My knowledge and probably also the workshop. I just got a call for help, from a pretty young woman (of course old bag wants to help) that the workshop doesn’t do anything, because so was not built and said that is not the rotary pusher installed, but a membrane. What it probably is that the machine is not running anymore or just sporadic. Before I go to work Friday and will watch the live e i like to ask… Were there conversion kits?
