The Cessna has a Continental engine while the Piper has a Lycoming?
The Continental is perhaps more prone to carb icing especially in a long glide approach. The Continental engine can be more difficult to start when hot, although that's not much of a consideration to be concerned with in Britain.
It is perhaps marginally easier to close the mixture in a Cessna instead of the throttle than it is to make that mistake in a Piper.
The best solution would be to read the handbook and try to remember which aircraft you're flying. It's a struggle for an aspiring dictator of course but then so was Mein Kampf.
