Walbro WT 419 Carb help!!

Hello I could use some help with my Homelite blower that has a wt 419 carb and the problem is that the primer bulb does not suck in any gas no matter how many times i press the primer.. I took apart the carb and replaced any bad gaskets and cleaned it thoroughly.. I tried dumping the carb into a small container with gas to see if it will suck gas in but nothing at all!! The primer bulb is new so i dont know where else to check.. Please any help will be appreciated..

Did you replace the fuel lines, make sure the filter is clear, and replace the carb gaskets and diaphragms?

Sounds like the check valves in the primer assembly may be bad.

Thanks but do you mean the red button thing that the primer bulb sits on?

Yes...that would be it. Some have different styles, but that one is easy to see and check. Can you spray carb cleaner through the hole in the center of it?

But air doesn't push out the return line on the carb? Does the primer bulb even move? If it doesn't push air out, and doesn't pull air in, then the primer can't move, correct? Unless it is moving air through the valve in the carb body that goes through to the throat of the carb. If so, this part is non-serviceable.
