Bendix PS-5C Mixture too rich at full rich position

[patreilly]

The PS-5C carb on my ASII seems to run fine except at full rich setting. It is too rich and needs to be pulled out about 1 3/4" to run well. I have the old old Bendix manual with all kind of cute drawings in it. But, I can't seem to figure out how or where to adjust the carb to lean the mixture control to run properly at full rich setting. Can anyone tell me how to adjust the manual mixture to proper setting at full rich?
