Tech information furnished by Rich Adams
The schematic is from a '84 Emissions manual. I had/have the same components on my '85 60. Modified to reflect a "de-smogging".
Jim wrote vacuum switch and primary advance on the right side of the component drawing. That part of the drawing represents the pipes on the passenger side/base of the carb.
I left some items in place on the schematic, such as the EGR piping and wires, remnants of other things removed.
