It's not often that I can post an absolutely definitive answer to a point raised here - but this time I can, and provide evidence to boot.
My jodel has a Continental C 90 -14 F and has the sort of carburettor with a the mixture control that won't provide idle cut-off; just mixture leaning at altitude
So, the only practical way to stop the engine is to turn the mags off via the switch.
Turning off the fuel results in a very very long wait indeed; pipe and gascolator have a fair bit of juice in them.
It's been this way for ever, with the previous owner as well, and has operated in some very hot and some very cold areas of Europe, if you think that's a factor.
I can definitely put the "exhaust explodes" myth to bed.
I've 'dead cut, tested' hundreds of times - zero result.
I'm very amused by people saying ' it's not in the checklist !' - come on, really !
I have a mental checklist for going out the door to work every day ( phone, wallet, keys, lunch, if you are interested)
but it's just an aide-memoir, not the gospel.
Myself, I take the same view of check lists for aircraft.
But then I've noticed that there are two sorts of flyers- those that get their thrills from learning lists by rote and memorising intricate procedures and sticking to them blindly , and those that like to fly places and do things.
The second group have a much more exciting life - but possibly shorter with a very positive full stop at the end.
You pays your money and takes your choice, but I think the first lot tend to give up flying after a couple of years.
Is it like ice skating to them? By this I mean, it's only fun when you can't do it very well - after you get proficient it's just endlessly going round and round in circles.
By the way, despite lots of advice to ' save the battery and starter motor' I never prime and pull blades through by hand any more on mine.
I never want what I call a "Luscombe surprise "; seems like a bit of fuel or fumes can still cause that even when the engine has been stopped the conventional way.
No Luscome pilots were harmed in the making of this post- don't troll me!
