need help finding a carb
 

its for a old cast iron 16 horse briggs single cylinder, the numbers on the shroud are 326431 0190-01 7703041. ive found plenty of carb kits for it. but im needing a actual carb, its the updraft style carb, or any hints on other carbs that may work with it? not to worried with the governor setup, i can make something work as far as that goes i just need this thing running and the old carb is pretty much a paperweight. its what i use to drag out the fallin trees in the timber by my house so i can chop it up for firewood. thanks for any help guys.
