Washer spins slow or needs help to spin

Older washer needs replaced but need to keep it running a bit longer.
Just started not spinning fast enough, sometimes needs to be hand spun to get it going. What would cause this? Does the clutch need replaced?

Would be grateful for any help.

Thank you

clutches possibly coated with oil from tower assembly or just worn out clutches. If you can hand start and it gets up to speed this would apply. If the unit will never get up to normal spin speed , a piece of clothing or other materieal may be between the inner and outer tub.
