electric start to pull conversion

Have a Snapper push mower with a B&S single cylinder engine 121S07-2116-F1
Engine family  BBSXS.1901VA
 
It is an electric start with a bad starter. The starter is pretty expensive so I thought to convert it to pull start with some used parts.
I know the correct fan, cup and winder to use but I need to know what the correct flywheel to use would be. Does anyone have a part number? I have the engine diagram which shows both flywheels (for pull start or electric starter) but only shows the part number for the electric starter flywheel.
Any help is appreciated.

I'd think the current flywheel would work fine.  
 
You just won't be using the flywheel teeth to turn the engine over as your now
going to be using the cup and pull starter.

thanks...........I will give it a try with just the cup and see if it fits the current flywheel. Parts are on order.
