I just purchased a 2003 Bergman AN400 with 9600 miles on it. It runs great. The only thing I have a concern about is when I pull out each time it makes a noise from the rear end and quits as soon as you are moving like 20 feet or so. Is this common for these? Shouldn't be the belt at 9600 already should it? They say 20000 miles for that usually. It does this after every time you stop and pull out again. Thanks for any input.
