What to do

- Inspect the control cable for fraying, stretching, or disconnection at either end.
- Adjust the cable tension per the manual if there's an adjustment barrel or turnbuckle.
- Clean any dirt or debris from around the clutch or engagement mechanism.
- Check the clutch plates or pulley for wear if accessible.
