Troy Bilt TB430 carb issues

I bought this leaf blower last year and it ran great all year long.

This year it will not run unless I pour a bit of gas into the carb.

The primer bulb was not filling up at all so I bought a new carb, fuel lines, and filter and installed it.

The primer bulb still won't fill up.

I know the blower runs because when I put some fuel into the carb, it will start and run until it runs out of gas.

I just can't seem to figure out why the bulb will not fill up when pressing it numerous times because I have new fuel lines and
new filter on it.

I have checked all screws and they are tight. I hear a little whistle when I press the bulb but can not find any leaks.

Does anyone know what I should check next? This is really frustrating. I can work on 4 cycle stuff just fine but 2 cycle dtuff just kills me.

Thanks for any help!

Jim
