I am assembling a "framed" 26" bike and and its been over 20 years since I have put a bike together, so forgive my ignorance. The instructions don't say on the front wheel if the washer is suppose to go to the inside or outside portion of the frame between the two nuts. The outer nut has a lip (washer like) built into it, while the inner nut does not have this lip so my common sense tells me the washer should go to the inside so there would be equally proportional surfaces on both sides of the fork mount, but I don't like to assume anything so I thought it best to just ask the professionals here.
