Open the main needle about four turns and don't worry about the idle until you get the top end set. If it is too lean open it another turn. Once you get the top end set you can mess with the idle. You have to get it to run before you can do much else with it. Even if that valves aren't quite right, as long as they aren't held open it will run if it gets fuel, has a good plug(s) and and isn't broken.
