I had to replace the clutch on my CT4S.
The Manual says the set-screw needs to be 4 full turns out as recommended or to have the factory settings as a starting point for further adjustments.
Now, if I turn it 4 turns out, the screw is too far out and locks the outer housing wheel.
The most turns out that it still spins is 3 turns out, is that O.K.?
