ok.. and do get some real Starter Fluid.. it's very volatile as compared to carb cleaner..
It's made for starting cold engines.. mostly ether but it has oil mixed in.. a little bit wont hurt the engine but the price is kinda stiff, like $5 a can or so.
Another thing that can prevent gas getting in is a hung-up float. On some carbs the float bowl can be reassembled wrongly and interferes with free movement of the float. A bent float hinge pin might do it too..
