I just bought this really nice looking 1980 V50 30MPH model and got it running, kinda, it sputters constantly,I changed the plug, no change, I cleaned the points, no change, I changed the coil wire and end, no change. The carb was pretty clean inside and does not leak any gas so I think it is OK and it doen't run any better with the choke on. I believe it is an ignition problem. The engine will idle or run wide open, sputtering the whole time. Since there are no holes in the flywheel, I can't see if the points are sparking excessively. This is my first Motobecane (not counting my parts bike). Any ideas would be appreciated.
