A couple of years back it developed a small leak at the primary throttle shaft. I sent it in for bushing installation and following that I did a bebuild with a Jiffy kit. I lost the choke pivot pin (nomenclature unknown) that connects the piston to the lever inside the electric choke. I found that a smooth paper clip, cut down to length fit nicely in the tiny bore. Time has gone by and after doing other work on the motor this AFB is on despite several attempts I can't seem to diengage the fast idle cam, unless I manually disengage it by reaching under the air cleaner and doing so. It may be related to the repair I mentioned above but I'm dubious. There's no binding in the linkage that I can determine.
