Lesson learnt ! No fuel in gearbox but drained oil anyhow. OIl pump side dry. Will have a look at alternator side tomorrow as the machine is stinking in an outhouse now in disgrace. New float and needle ordered. The carb float bowl is a concentric therefore the theory is angles make no difference unlike say a monobloc, but they do not have the best reputation...I wonder if anybody has fitted a Japanese carb at any time???????.
There are 2 allen grub screws left and right in the crankcase below the crank line. I guess they are oil drillings plugged not crankcase drains.
Being a Mk 1 Silk my petrol tap can only be accessed by taking off the LH side panel so my normal practice of switching off fuel 10 yards from home cannot be done unless i leave the LH side cover off but as that contains the tools I'd rather not do that. One of my other bikes a Morini has an Electric tap which is great but it means the carbs always have fuel in them, but at least when the ignition is off the fuel is cut.

Back to float valve needles. I fitted a new one after I flooded the engine after leaving the petrol tap on overnight. Made no difference, still floods if left on the sidestand. I think the angle when on the sidestand is too great for the float to close the valve properly. You only leave the petrol tap on once!
