You guys obviously didn't read my whole post. I stated that you can get filters at any shop, a filter is a filter is a filter.
Getting parts other than filters for that motor will be almost impossible unless you go through JD. I know this because we work on these things every day. If I call B&S and give them the model, type, & spec on a B&S motor that is in a JD the first thing they tell me "Oh, Mr. Gamble, that motor is locked in by JD, you will have to contact a authorized JD dealer. But here is the part number and we do have them in stock but you will have to pay what JD wants you to pay for it, sorry!"
No lie, that is the an exact conversation I had with one of the B&S reps before. Just laying the information on the line...
