As you didn't include the model bike this is on in your question, I searched through some of your posts to try to Sherlock Holmes what bike you are working on..... CB750K1?? As a former parts manager, please include your model when asking for parts help(and even asking for mechanical help) so you get the correct parts help and we don't have to ASSUME what bike you are asking for help with. Many members have more than one motorcycle....

As to carburator link cotter pins. Honda only lists the diameter, 1.0mm. They don't include the length. But, in the part number, at the end, one fiche shows 080 and another fiche shows 010. That would be 8mm and 10mm lengths.  If you get 10mm length you will have enough length to fold it over. Or if you have a local hardware shop get both 8mm and 10mm length.
I hope that helps.

I always get them from a hardware store - different sizes and use what fits. I also used just a piece of wire and it works fine.  There are no big forces in the carb linkage.

 I have also used the little hairpin type clips from the assortment in the HELP (misc. universal parts) display at my local parts store.

I couldn’t find any cotter pins small enough to fit.

I ended up using these.

You want an M1 x 8mm split pin. and they can be found on eBay. A bag of a few hundred costs $5-$6 at most.
You only go around once in life so it might as well be on a motorcycle.
