For those that ever run into the problem of breaking/losing the choke cable pin/fastener (see brass fastener above green arrow, where the cable goes around), DO NOT use a standard bolt and nut to repair this. That fastener assembly is designed to PIVOT due to the fact that you are moving the choke lever in an arc. If you use a standard bolt and nut you will clamp the little brass pulley and not allow it to move. The result will be 1) non-smooth movement of lever, and 2) eventual fatigue failure of the choke cable. I learned this from personal experience. The previous owner had used a standard bolt and nut, and one part of the cable failed on me. I had to purchase an entire choke cable assembly to get new cable with proper fastener. It's an expensive lesson.
