You still using those Japanese SU's? If so warm it up and try starting it with some choke applied, this might richen it enough to fire! ( the choke is simply a cam or ramped shaft that lifts the piston/needle out the jet while still blocking off the air intake to create a greater depression in the carb/manifold ) no accelerator pump on these dinosaurs.

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?
