Gents,
can someone tell me why Triumph used the flexible mounting system on the original cars, please?

Plain and simply - "Vibration" stops the carbs from shaking.

Basically what Paul said.
Early slant engines have Strombergs which have a simple rubber gasket between the inlet manifold and carb body. The carbs are held on with nuts and spring washers which absorb any vibration transmitted from the engine to the carb. The theory is that the carb is isolated it prevents the fuel 'frothing', it's the same setup on DCOE's etc... I spoke to someone from Burlen once and they told me that SU's had more of a tendency to allow the old 4 and 5 star fuels in the '70s to foam up in the float chambers causing fuel starvation issues hence why they had to have a thick mount on them on some cars.
Modern fuels I believe have anti foaming agents added in to them to prevent problems with the modern high pressure fuel systems so the rubber gaskets and rubber mounts aren't really necessary any more.
