Super pictures, thank you for posting them Andy. Most interesting to see the very cold carburettor. As my flight instructor once said, "Inside a carburettor, it's always winter." i.e. the evaporation of the fuel causes a significant drop in temperature and, in an extreme case, inlet manifold icing. On one of my cars. a '29 fitted with a side-draught SU suffers from this. The cure is a hot-spot, created by the application of several turns of wire wrapped around the exhaust pipe and inlet manifold.
On a piston-engined light aircraft, when it flies into a different flavour of air and suffers from ice-accumulated misfiring, there's a lever to select "Hot Air". The ice then melts, the engine misfire worsens, the pilot panics thinking he's made it worse, switches off hot air - and the engine stops.
