If the floats are sticking the carbs probably need a complete strip and clean/rebuild. There are quite a few You Tube videos on rebuilding Amal carbs. Or you can do like I did with my Norton 850 and go with Mikuni carbs.

Back in the day I have done many of these swaps and the Mikuni are indeed a much better carb than Amal.
As I 'member the Amal floats are sealed brass. Check for leaks and clean with gas or Brasso!
Old carbs are interesting. They either come to life or never work.
Get yourself an ultrasonic cleaner and put some carb cleaner it it. Run it for 15 minutes inspect then maybe 15 minutes more. You can pick one up cheap at Harbor Freight.
There is a British Motorcycle Mechanic page on facebook I highly recommend.

[QLikeUOTE="breeze, post: 616486, member: 3811"]Amal carbs on my 72 bonne the floats are like hard plastic with metal pin to let them "pivot" I have used regular gas and a tooth brush[/QUOTE]
Brass v. plastic - I show my age advantage over you, my friend!
Most often it was grime sticking the pivot pin anyway, and not the actual floats.
