Default Re: Acorn vs. Hex Nuts

I have 2 engines with acorn nuts and the nuts are solid steel nuts and not 2 piece " pressed on thin metal stamping" or anything of the sort, but I say if someone wants to change theirs more power to them and if not then just run-um like most of us do and dont worry about it. make sure they are tight so the head is torqued the way it should be.
