Loose Flywheel

[hailia 0]

I have a 1962 725 with the original briggs 19 in it. My problem is this. The flywheel one day suddenly loosened up. I pulled everything apart, tightened up the nut, put everything back together, started it up and the flywheel loosened up again. It looks like all the parts are there per whatever sketches I can find from briggs or simplicity but it just won't stay tight. Can anybody enlighten me? Thanks

Well this looks like a repeat of a preveous post, how ever i will repeat ( if torgueing to 100 ft lb and installing security cage does not solve the problem ) replace the flywheel as damage has been done to both crank and flywheel.As stated before i have a good flywheel you can have just pay the shipping.
