Flywheel nut size on Craftmans mower?

I need to check the key under the flywheel for replacement, but don't have a socket big enough for the flywheel nut. I am wondering what size it is so I can go get one? I'm really not good at eye-balling things like that.

It's a Craftsman Rotary Lawn Mower Power-Propelled 21" Multi-cut. Model No: 917.370733

If it has a Techumseh engine, it should be 3/4""... Roger

Looks like it is a Briggs engine so 15/16 socket
