Don't know what else to tell ya...........the spinner adapter nut is what it is.........put on your helmet and flak jacket before you start the engine I guess........I've been wacked with props off of 4-strokes before and I survived.............now that I think about it, I believe thats when I learned to swear............................................. ....

I've got your same engine and spinner set up and like I told you.........I like mine.
