With regard to the clutches, the machine only came one way and it uses both.
The 200ES (and most auto-clutch machines) uses two clutching systems:
1. The centrifugal system is what disengages at low engine RPM to allow you to come to a stop (and not kill the motor)
2. The manual clutch system is linked to the shifter and actuates when you push on the shift lever
There is also a one-way bearing as part of the centrifugal system, and it is a common place to have issues. However, if you aren't having troubles with these, I'd leave them alone. If you have to change anything, I'd stick with OEM friction material if possible.
Are you having some issues that may be clutch related?
