I've tried that with some success, but usually end up driving the nut thru the prop. I think i figures out today however, in my Idiocy, I was trying to drive it down with just the prop and the nut (without the prop washer) I just thought there should be an easier way. Thanks for the Reply and upon my next bearing change, I will try the prop washer on top next time By the way (which may require another post) anybody know where to buy good, discontinued OS Parts for the 46Sf (ringed) or bigger OS ringed engines such as Drive washers and 4D carbs? I don't know why they quit making the OS 46SF, I can say that is the best enging I have EVER used on a 40 size (ultra stick or my Mustang) any URL's would be appreciated.
