ooh dont like that!
The first thing to do when faced with an engine failure is to adopt a gliding attitude and reason why its stopped and attempt a restart. Do this as quickly as possible, if it's carb icing you will be glad you did.
High key/ low key is about picking a downwind point of around 1500 agl not crosswind.
Adopting best endurance speed is as useful as tits on a bull on a light SE aircraft, stick to simple basics!
