I'm not sure that I've heard of a passivation process being applied to a zinc coating. Perhaps more likely, the platers had some tricks up their sleeve to get a zinc plating with a specific look.

Most carburettors are made of aluminium alloys; I don't think I've seen one with zinc plating.

There are kits on the market to carry out plating by means of a cotton swab on the end of a graphite rod, that is dipped in a plating solution and then used to do electroplating. I've seen quite good results from them, especially when the area is small as in your case. They may well be worth a try.
