Good afternoon speedy. What is the Model, Type and Code on the cowling?
I have a 450 series Model 9T502, Type 0141-B1, Code 10082651 and just went to the Briggs and Stratton website to get part numbers. As they need 6 digits for the model, it was easy as adding 0 to make the Model number 09T502 with type 0141 in search.
According to my mowers reference, the part numbers for the Flywheel are 79968, which replacement part number for mine is now re-order part number 592370.

Link to my engine manuals is:-
