Wow, excellent info and thanks...
It almost seems like the starter is spinning without engaging the engine. How hard is it to improperly install the starter so that the starter shift isn't lined up with the proper gear? I popped the starter into place and was able to line up the bolts with no issues, but could I have missed something while reinstalling?
I only wonder because last fall everything worked just fine (no issues or odd noises when starting), and I'm trying to rule out an error on my part in putting it all back together.
