I guess I wasn't specific enough. I never turn off the mags on a running engine which has a conventional carburator equiped with the idle cut off feature........ which is Oh, I would guess about 97 % of the GA aircraft out there.
I post information which is relevant to the majority of the aircraft out because it would seem to me to be of the most use.
You will always be able to find the exception to just about any of the advice I post but it would seem to me that you are implying that my advice is not correct because it does not apply to
your aircraft with its obsolete and now very rare carburetor set up.
I would suggest that a better take away is to note the importance of understanding aircraft systems particularly when you are dealing with rare and/or unusual and/or old aircraft but that there are many best practices which apply to
all the common Cessna/Piper/Grumman/Socata aircraft fitted with 4 or 6 cylinder non turbocharged Lycoming and Continental engines.
Also I corrected my post. I of course meant to type switch to "off" and listen for the engine to die not as I had originally posted switch to "both" and listen for the engine to die.
