Sounds like you are going to need a new starter if your battery checks out. I had a similar issue where the starter just wouldn't spin up fast enough to engage the flywheel. Well after replacing the battery and not solving the problem I pulled the starter and a mechanic bench tested it. Was spinning but the brushes were so worn that it just didn't have enough umph to get up and going. New starter and she was running like a champ.
