These particular Bachmann engines are known for the problems you are explaining. I have one sitting in its original box that needs to be sent in to Bachmann.
You won't find replacement parts for this. Your best option really is to send it in to Bachmann for "repair". They won't repair it because they don't have the parts, and will replace it with an equivalent engine . Visit this page for those details:
