I've got it figured out...at least for a smaller engine. The one-way clutches that aren't hard to hard to get can't handle a whole lot of torque, though. I'd be ok with a 1-litre engine, but nothing much bigger.

Option B is an electric clutch - like aPTO clutch from a ride-on mower - but they too are limited on how much torque they can handle. Unless you want to spend $$$
