Echo Backpack - Pulling my hair out!!!

So, I have an Echo PB-403T which ran great for the past few years. Lately it has been bogging out at about half throttle and spitting gas out of the carb. Blowing leaved at that speed just isn't fun, so I removed, thoroughly cleaned and rebuilt the carb with a Zama rebuild kit. put it all back together and it's still doing the same thing. It's spitting gas back out the air filter. Doesn't matter how I adjust the high speed screw, it still blows back gas out of the carb.

Does the PB-403T have a reed valve on the intake? Am I missing something? I'm pulling my hair out on this one.

Thanks for your help. WB2GLP
