Scooterotica

I'm at the end of my tether with my Vespa. If I leave it for a day or so I can't get it started. I've got to push the choke back in, hold the throttle open and kick it about 20 times before it will start. Once it starts it runs great. I've cleaned the carb out and it's still the same. I've also replaced the HT cap to an NGK one ( it had the orginal one on). It's from 1979 and is in great standard condition with only 10,500 miles on the clock. I think it could be piston rings but those engines run forever when standard as we know so well. So any ideas????

not being physic, and it being 30 years old... blocked pilot jet, worn float needle, perished wiring, shitted up petrol tap. oh, and worn out stand feet, they make the scooter stand at an odd angle, and the carb floods as a result. change the float needle for a red tipped one, and the stand feet for new ones, and see if it still floods/doesnt start.
