If you'd like to be on the safe side, you can get a carb kit, just in case. Otherwise, disassemble the carb and inspect it to see if you need any new parts.
The kit includes a new float, needle/seat, and a few other bits, including a couple of screws and gaskets. Generally not needed unless the carb has a lot of hours, severe "sludge varnish" in the inlet needle area, or if the needle/seat has wear from imputities in the fuel. Typically, on low-hour, good-fuel carbs, the only bits you might need from the kit are the needle and seat. If you get a kit, I would recommend the Factory kit from a dealer, Part # 3V1871220M, $33.42 MSRP.
