Hello I have a Pioneer CT-F9191 with the tape not forwarding/ reversing. when on play it will turn a few seconds and then shut off. (the right reel doesn't spin) I have replaced all belts and sent the clutch to be rebuild by Mark. He said the clutch was fin no cracks but he said he upgraded it anyway. I noticed that the spring holding the clutch arm is a bit stretchy, but I am not sure that is the issue or just part of it.
