The carb currently on it is a replacement, not exactly the original. But reasonably new.
If you don't know the history of the current carb, I'd buy a kit for the original, boil it out to clean it well and install the kit, paying careful attention to the float level. If it has a composite float instead of soldered brass, buy a new float, too. Composites can change density over time and lose buoyancy.
