Looking for small part help

[Argent]

I have a CFMOTO Legacy 250, which is a rebranding of the V5.
The engine and CVT are a clone from the Honda Helix 250.

On the fuel enricher auto choke, there is a C-clamp holding it on, that C-clamp is secured by a tiny little screw. Does anybody know where I can get one of those tiny little screws?

Or know the size and thread count so I can go shop at the hardware store?

I don't need a new enricher, but I'll be happy to buy one if it comes with that tiny little screw.

Thanks!
