I don't think it would hurt. I think that if I couldn't get the stop motion clutch knob to disengage the needle movement, I would do as Peckish did. Have you tried holding the white part of the hand wheel and turning the silver knob in the center? Does the silver knob move at all when holding the white part still or turning opposite (like twisting a bottle cap)? Seems to me that one time, I made sure all the parts were positioned correctly that I did hold the take up lever for just a bit and then let go and then it continued as it was supposed to.
There are four positions for the washer to be placed and only one correct way. It seems like I have a few machines that it is hard to tell if the inner tabs are bent and which direction they go.
Here are a couple more pages that deal with what I'm talking about.

Please note that some of the pictures are shown with Clamp Stop Motion Clamp Washer with it upside down (not the proper position) for showing the purpose of the Stop Screw. ....
