Stihl fs90r head will not spin

[George Cox]

I am new to this site. Just signed up today. My Stihl fs90r head will not spin. My clutch is turning do you think it could be the cable. Any help is appreciated thank you

Yes, cables and /or shafts break and are easily to replace.
Split the unit and they just push into the back of the clutch for cables.
If it is a strait shaft then the shaft & clutch drum are usually braised together.
Also strait shafts have a bevel drive at the end and these canwear as well.

It could also be the gearbox so check that out.
