Thanks, found the nipple to attach to this morning. Just needed to look a bit harder. Unfortunately the parts fiche doesn’t show the choke part, but I believe after some more reading last night it is a spring loaded choke plate. Allows the choke to open when there is sufficient vacuum.
Follow up question. Part 16 in the carb diagram is the air cutoff valve cover, however I do not see an actual acv in the parts fiche. I definitely do not have anything installed behind that plate. Is this correct? Thanks again.
