Honda GX35 Broken Part/Need Help Idenifying

Howdy Everyone,

My Honda Versattach UMC435 got dropped on the power head and a plastic part came off. The power head no longer will idle. It either has to have the trigger pressed to run or it bogs and dies when RPMs get low enough. I was not the one using it when it was dropped so I have no idea where the broken piece came from.

I’m guessing it was somewhere near where the throttle line enters the power head/carb, but I can’t clearly see where anything looks broken off. I’ve attached photos of the broken part and the powerhead. I’d be extremely grateful if someone could tell me what part I broke or what replacement part I need to buy.

Anyone know what’s broken based on the attached pictures?

Much thanks in advance!!
