Small metal object with clip on top. Clip spins around the object body and can be attracted to a magnet (so made of steel probably). Object body does not react to magnet (so made of brass maybe). Cone shaped tip seems to be made of some kind of plastic.
Found this in my back yard, probably from something I was working on, but it doesn’t look familiar.
What is this thing? (Identification may help me fix something I don’t know is broken!)
Spot on.
Only no hole in the tang, the clip slides over the tang so the needle can free float as the float itself moves.
In this diagram, the float/needle/seat are #22-25
Also, (for OP) - the needle tip is made from a material softer than brass, so it wears out before the seat, since it’s easier to replace.
I’m more used to motorcycle carbs where that needle has a post with a spring under it.
