Yup - brass setup - unscrew the whole "body" of the choke ass'y and you'll see what I mean.
It's just a plastic knob on a brass rod. I would imagine super glue or good old JB Weld will work for a temp, gotta go play, fix. Look in Dennis Kirk - I think they have both a replacement piece and a cable conversion - well, maybe not since it's idle control too...
If it were a TMX, the stock choke assy would bolt in and you'd be able to use the dash mounted pull knob.
