The Sprag Clutch has been mentioned a few times. Could someone explain to the group what it is and how it works on the 912iS?

It is sometimes referred to as the "slipper" clutch and it does just that - it is designed to 'break free' at a certain torque value, to protect your engine in the event of a prop strike, for example.
Have a look through the 912iS Heavy maintenance Manual - section 72-20-00, that will give you a good picture of what the sprag clutch is made up of... ( see https://www.rotax-owner.com/en/support-topmenu/engine-manuals#912-i-series-engines )

Thanks for the explanation. What is the Sprag's involvement in the start process?
