Thanks to SMTCapeCod.

I was worried when I discovered the WUR I was sent from a CIS rebuilder had the bosch part no. 0438.140.036. In the WSM it shows fuel diagrams for various WUR models. it shows part no. 0438.140.086.
Well the tech spec shows something different. It shows both WURs, specifying .036 being for 80 models and .086 for 81-83. They show identical fuel curves, so I dont know what the difference is, but just in case anyone is ever in my situation, here is the diagram.

Yes, 036 and 086 seem to be the same, but they are NOT the same as .087 - look at the scales - first diagram on left has highest scale at 3.0 (Bar?), other two top is 2.5.....
jp, with 086 still....

... and the slopes are different, too.
