I was working on my dads yard machine the other day (model #13AH670F062) and accidentally knocked the spring off the shift lever,(part 85 in the frame, drive, wheel, and rear section). I can't make out how it goes back on. Does anyone have a clearer picture or could anyone guide me. All the parts diagrams I've looked at are not all that clear. There is a few different ways to put it on, but none of them "feel" right to me. Thanks for any help.
