I have a 1971 sachs hercules. When I bought it it did not run. I have replaced a few basic things such as the spark plug. I have also cleaned the carb and the pionts. It runs now but I don't have an owners manual so I was wondering if anybody could tell me some specifications such as gas mixture and tanny fliud. I would appericaite any advice that you could give me it is my first moped.
