Your Owners Manual 's here

If that doesn't go to sears parts direct and search manuals with your sears model.  If it is a tractor part sears is your best bet.  Call the 800# and tell them what you want.  If it is attached to the engine go to a Briggs dealer with the B & S numbers and they can help you.  Make sure you bring all the numbers to the dealer. The B & S model you gave is really model# type# and code#.  I think the code would be 701.  If this elbow is part of the carb you may have to purchase a new carb.  

Good Luck on your project.
