I´m having the same problem with mine right now. It turns over..goes er..er.er.er...your starter is probably shot. You can pick up a brand new one off ebay for around $105. I´m going to do the same. I had another 81 prior to the one I have now, took it in an had the starter rebuilt, and it still cost around a hundred bux so this time i´m just puttin in a brand new one.
