Yeah, in most cases you can disregard any recommendation for a single-weight oil over a multi-viscosity oil if that recommendation predates multi-viscosity. The performance of 10w30 and SAE30 are going to be nearly identical when hot. The difference is that the 10w30 will flow a lot better when cold and cause a lot less startup damage.

If your current carb is sufficiently corroded / damaged, you'll be fighting poor sealing on it even with fresh gaskets. Some carb designs tend to be more reliable and easier to live with, as well (i.e. every Solex two-barrel that was replaced with a Weber).

If it's something that isn't known to be nightmarish to rebuild or live with I'd probably rebuild it then. Hell of a lot cheaper than a lot of new carbs on the market, plus the pain in the rear end of adapting your throttle / choke linkages and the baseplate.

It's also a carb; it's not like if in the future someone gets their hands on it and decides it needs to be 100% original, it will be irreversibly modified. You're doing the car a far bigger favor by modifying it so that it can be easily and reliably driven, versus kicking yourself in the nuts repeatedly to keep it perfectly stock.
