ef2800i wont start

i stored my ef2800i after hurricane katrina 3 years ago and today it won't start. oil is new and fuel is fresh. a little carb cleaner sprayed in the throat will get it to run for a few seconds but then it dies. obviously, it's not getting fuel. thoughts? i've seen a schematic of the carburator that you sent to someone on this website ... can you point out proper settings for jets and how to clean them, maybe tell me how to check the float and its settings, and any other thoughts that i might use to diagnose and cure this problem. oh .. most importantly, how much is the service manual and does it do a good job of covering the engine?
