I have tried everything to get my Motobecane to run and idle properly, but nothing has worked. There is simply too much gas getting through the carb. My sparg plugs keep getting covered with a dry, black soot. I have tried smaller jets, adjusting the choke, adjusting air screw, etc., etc, etc. I have spent probably 15 hours trying to get this moped to run the way it should, but nothing has worked.
Could my carb just be shot? Do they just wear out internally?
