If you have played with carb by using lighter oil in the dampers etc the piston might lift a bit much after a hot soak when trying to restart and kill any signal at the needle/jet. Try holding the palm of your hand over the carb inlets while cranking- does it fire straight up then?

Worse still, I WISH I could use the Jap SU's the 240s get to use. I have to use the 260Z one year only Hitachi flat top SU types (don't think anyone but the US got these great carbs and for one year only since the 260Z was a one year only car here) which really are an ugly duck.
I've messed around with oil in the dampeners and will do so in depth next week again to mess around a bit with throttle crispness. Didn't seem to have an affect on the hot start. Ditto on the enricheners and ether spray, didn't help at the last outing in October.
It is amazing how easily it'll fire up on a push start. I don't need to anything other than drop the clutch on it in 1st or 2nd at basically a jogging pace - blamo, fires right up.
