Much hotter than the fan housing, which ought to be cool-ish with the engine fan running. Also check for a tank vacuum again - if you've got a partial breather blockage it might leak down quick enough to restart after a few mins.
It might be evaporating fuel, before it gets sucked in the cylinders ,in fact to do that you engine will have to be running very hot... But I am a novice on type 4 motors ...
I do wonder about French petrol. I believe e10 generally runs leaner and therefore hotter... Perhaps there is more ethonal in the French stuff than here (e10 doesn't mean it has 10% ethonal, it means it has between 0% and 10% ethonal).
Could even be the opposite and be Carburettor icing - though a fuel issue seems much more likely. https://en.wikipedia.org/wiki/Carburetor_icing IIRC it's a centre mount progressive carb on a type 4, so the inlet manifolds are very long and I don't know if there's any heating. Hope you get it sorted @SeanOC - Mrs.T sends her best wishes as well.
i think coil could be a good shout, you drive it a bit it gets hot and cuts out, stop for a bit it cools down and then starts and drives fine a gain for bit etc etc etc . just like classic minis when their coil goes.
Yeah bu tit could be breaking down from the heat, the heat you are feeling could be enough to kill it
Ta & to Mrs T I don't see it as icing, both days it was 30-35C+ and the engine bay was dammed warm. I also have a warm air pipe fitted to the base of the carb
Just got a little more interesting, for me at least. I asked the driver where to get water b4 he left and he pointed through a gate. Just went to get water and I am sleeping next to a Cemetery! May be woosy but glad of the road light above Cyril LOL
