As you will notice on the second of the two side views showing the linkage, there are only two springs. The top one connects directly to the butterfly valve mechanism on the top of the carb. There are two connection holes in that mechanism. The top spring is connected to the outer most. The lower spring connects to the aluminum housing in the foreground.

Unfortunately, at the time I disassembled the carb, I did not take any pics)(big mistake) primarily since I believed there would be docs and pics online which could give me the linkage set up. I even went to a retail outlet to find similar models to get an idea. Of those, the linkages were either covered up or updated model which did not match mine. PDF versions of owners manuals did not cover this detail. So, thats why I showed up here, lol.
