Power Clear 418 ZE Over Priming... WHAT GIVES?!?

Hey folks,
 
So, I snagged a free snowblower off Facebook Marketplace—because who doesn’t love a good project, right? Had an absolute blast taking it apart and learning the ins and outs of how these machines work. Got it to start, but... it idles rough.
Figured the carburetor might be the culprit, so I gave it a good soak in a Pine-Sol bath overnight (that stuff works wonders sometimes), but no luck. While poking around, I noticed two screws on the carb: one was already looking pretty sad and stripped, and the other seemed to have no notches at all. I think one of them was for adjusting the idle, but honestly, I’m not 100% sure.
In my infinite wisdom, I decided to try removing the screw to check things out further, but, yep, I managed to completely strip it. At that point, I threw in the towel and went to Amazon for a replacement carburetor. Found one that matches the part number (#119-1980), slapped it on, and... now we’ve got a new issue.
When I press the original primer bulb, I get a small stream of gasoline dripping from the carb. I haven’t tried priming with the cover off yet, but my understanding is that the primer’s main job is to send a little gas through the main jet. Nothing else has changed—same gas lines and all—so I’m scratching my head. Blower sounds great when idling though.
Here’s the thing: I’d love to sell this snowblower, but this over-priming situation is making me a bit nervous. I don’t want the buyer to think something’s majorly wrong. Should I mess with the fuel lines? Replace the primer line? Or maybe I’m missing something obvious?
 
Appreciate any tips or tricks you’ve got!
Thanks,
