If the choke makes no difference, then it means that somewhere, there is an air leak into the intake manifold. It's probably a gasket issue.
You should also look to make sure the screws holding the top and bottom of the carb body are tight. even if they are a bit lose, you'll have trouble starting. And makes sure there is a gasket there too.

How does it run once it is started? If it has a good idle I wouldn't start pulling things apart looking for a vacuum leak. Try setting the high speed needle valve a little richer, in fact take it out and look for debris. Be careful of the gas that will come out if you remove it.
Hope this helps
