a fuel inlet needle can cause allot of running issues. they can also fill your crankcase with fuel. they usually come with the rebuild kit. its up to you what kind of work you want to do or if you don't mind doing it over if it cause's problems. if time is an issue which it usually is for me just do it right the first time and be done with it.
you can just take the carbs apart and clean the passages with carb cleaner and compressed air if the gas isn't varnish
