At the beginning of the summer my 81 cx500s water pump seal went out followed by the stator. Obviously a triple bypass was in order. Prior to this I had no engine experience. I own one manual and have read through the whole triple bypass article on the cx500 wiki. Engine is out and the rear case is removed, but I am stuck. The manual and the guide differ in their information and the guide says DO NOT PROGRESS ANY FURTHER WITHOUT SCRIBING THE ADVANCE UNIT. Unfortunately I do not know what the advance unit is, where to scribe it, and which parts need to be lined back up perfectly on reassembly. Pictures follow to show where I am. Any help will be greatly appreciated!
