It looks really worn to me also. Back when I had the use of a lathe. . . 🙄

I have managed to renew a point on something similar by chucking it up in a drill and running it against a whetstone.

I agree, that one looks very worn. Another way of restoring the point is to chuck the needle in a drill motor and secure the drill motor in a clamp or a vise. With the drill motor secured and turning the part, carefully reshape the tip using a clean, sharp single cut flat file. I have made a number of different small turned parts using this method before I got a real lathe. The biggest challenge with this part is that it is worn enough that a number of threads will have to be taken away to restore the point to a taper that closely matches the original. It certainly can be done, though.

Unless you can reshaped the seat as well
you’ll likely only be making things worse.
The shape of the needle mirrors the shape
of the seat. Changing one and not the other
can make adjustments so sensitive that you
can never get to a proper setting. If the
carburetor is not functioning as it should now
the solution is to replace it.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
