I need to replace the flywheel nut for an old 2 stroke Suzuki on a Toro 21" walk-behind mower.

I cross-threaded the old one so it's a little hard to match up using a sizer. It's the weekend and Toro parts dealers are closed.

Any chance somebody out there knows the size and I can run to a hardware store and pick up a comparable nut?

Thanks
