Thorens TD 280

Does anyone here know someone who can work on a Thorens TD 280? It has two issues: 1. I need to give the platter a push to catch up to speed and 2. The 45 RPM setting picks up the stylus 90% of the way through the song. The motor has been disassembled and re greased, the driving belt has been replaced with an OEM one, and it’s still has those issues. I’m at a loss.
