Need New Carb... but which?

I need to order a new carb for my 8hp B&S engine, but am not sure which carb to order.

The carb is marked Walbro 5-4993. There are various other markings as shown in the pictures provided below.

This came off a B&S Engine #192432-0122-01. The code on the ID plate is 9409131A.

Can anyone tell me which carb I need to purchase? Thank you.
