Change plug to a new one - many times the plug can cause this.
If you have good compression you won't have a stuck valve.
If you've cleaned out the carb and are sure the pilot circuit is clean, then use the normal starting procedure for this bike which is:
Kick until TDC
Press decom lever, move kicker so you're just past TDC
Release decomp lever
Bring kicker to top
One good kick NO throttle at all and it should fire right up.
Have you checked your valve lash?
You'll probably have to clean out the AP circuit too the diaphraghm might be broken or clogged up, but this should not stop it from starting it'll just make it bog when you give it gas.
Also - when you had the carb out and apart - did you put the plate on the slide back in the right way - right way is Curved side UP - a common reassembly mistake.
