" Hi again I desided to get the 1980 motobecane, and I got it running. But there are still problems with it. I am going to clean the carb. soon, but the front brakes won't work! when I pull the front brake lever, it goes down all the way, and nothing happens. it sounded to me like something wasn't connected, but it all is. when I made the front wheel go backwards just an inch, it worked perfectly. but the front wheel won't go backwards very far without jamming up. I disconnected the front brake and the front wheel acted fine. what do I do?"
