Why won’t it pull fuel, all parts changed, and still no fuel :(

I have no idea why it won’t pull gas. It was running one day and then it shut off one day and never again after. I changed the plug, all filters, lines, gaskets, and bought 2 different carbs, and it still won’t pull gas. I saw it splatter out “once” (with old pump), and never again. It wants to run when I spray engine start-up fuel into it, but it won’t feed itself. The exhaust is clean, so it is not that, unless I missed something. But it’s just not “pulling” fuel in for some basic reason, where I am just too noobish to figure it out. I tried fresh new fuel with and without mix, not a chance. I don’t know engines parts well, but I am a little mechanically inclined. I did a compression test, and after ~3 pulls, it hits full compression. 120? Iirc, bcuz it’s been a minute since messing with it.

I got this response below from another person in another thread. But I don’t understand some of it. Like specific part(s) or location of it on the engine to exam, sadly I’m just ignorant. If anyone can post pictures explaining the below, I would be eternally grateful. But I feel like the post below is what I am missing. The weed eater wasn’t stored. I used it every weekend. And living in Florida, that is most of the year. I just can’t understand what cut it off out of no where, and caused it to stay off.

@John, 2-stroke engines using a gas/oil mix requires pulsed crankcase pressure from the engine to operate the diaphragm type carburetor. A small port between the crankcase and carburetor allows crankcase pressures to operate the carb to pump fuel into the engine. If the engine hasn't been used, stored without performing maintenance prior to storing away for several months, the gas/oil mix can congeal in fuel lines, filter and may clog the pressure port feeding crankcase pressures to the carb.

Where is this pressure port? Pic? Ty!
