So below is some form of choke linkage retainer or clip off a Briggs 44R877 engine. This is off of my Husqvarna YTH24V48 riding mower. I've done all the research I could, checked every parts diagram for these engines i could find and I cannot locate a part number or even name for this part to be able to order one. I'm honestly not entirely sure what this part does, however I know there is some sort of interaction with the choke. This is a choke-a-matic engine if that helps any. For reference the bracket at the bottom is the throttle control assembly and the top is the carb bowl.

Item 1012 on the upper right hand corner of the following diagram Part number 592556
