The only way to know if your valves need to be adjusted, is to remove the valve cover and check them with a feeler gauge. Do a search on this site for "valve adjustment", and if you don't have one, I would strongly recommend a repair manual before you start.
As for the carb, if you have to use the choke to make it run after it's started, then your carb is not clean. You're gonna have to remove it from the bike and completely disassemble for a thorough soaking 24 to 48 hours in a good carb cleaning chemical following directions on the can, and then use compressed air to blow out all small orifices.
