TB 7/16 x 20 flywheel nuts (flanged nonserrated) for McCulloch engines.   Could use several.

I get them from fastenal.

Fastenal nor MacMaster Carr have the same thickness nut as the original in the non serrated. They are much wider and heavier. I found a source for originals.

Bill, can you share the source? Thanks. Ted

Ted, It was another karter that had a few of them. No Store or supply house has the correct ones.
