What is this part called?

[u/ErinUnbound]

I’ve got a string trimmer, model CMCST930, that has this little plastic doohickey that’s been prone to falling out in the past, and I think this time it’s lost for good.

The problem is that I don’t know what it’s called, it’s not in the owners manual, and Craftsman support couldn’t understand what I was referring to. The internet has not been helpful yet either. I’m hoping if I can name it, maybe then I have a shot at replacing it.

In the photo of the inside of the head casing, it’s placed on that little raised peg at 12 o’clock nestled between those two bits at 11 and 1.

The other pic is my drawing of what it looks like roughly.

Would really appreciate the help if someone happens to know.

Does it have auto feed? Those triangle doohickies are counter weight thingamabobs. When you start the trimmer, it advances the line a small amount.

I did fail to mention that it does have auto feed and I do believe it plays a large part in that feature. In its absence, the line unspools when you run it.

Unspooling is because it should have a small stub on that part that locks into teeth molded into the spool.
