Homelite string trimmer fuel issue - primer bulb?

Hey there,
I am working on reserecting a homelite string trimmer that was discarded. Compression seems good, there is spark, and I have fresh fuel, but, none seems to be getting into the carb. Pumping the primer bulb results in the fuel tank being pressurized and a squeek noise, but no fuel getting into the bulb itself. You can hear a hiss as you remove the gas cap after priming and the lines blow bubbles in the gas as you prime. I disconnected the fuel lines from the carb, and they are clean leading into the tank. ( IE I can blow air thru the lines towards the tank, - so I think the fuel filter is clear still) This makes me think the issue is in the carb itself. Does that make sense to you guys ( and gals) ? Any quick fixes to try? I am planning on tearing appart the carb next and cleaning it out as best I can.
this is my model

Sounds like a clogged jet in your carb. Try opening your choke plate and cleaning it out with a small wire.

Sometimes blowing half a can of choke/carb cleaner at it will help too. Soak it good!

more likely, it is a lugged needle valve in the carb.

There is tiny plastic tubing connecting gas in the tank and the bulb? Look for breakage etc in the tubing, particularly where it connects under the bulb.
Could be a tiny air leak at the base of the bulb, too. Squirt some wd-40 or even soap water around base of the bulb, look for bubbles.
I'm guessing its sucking air instead of gas.
