Hi Bouy,
That picture on the left side of your attachment is exactly what the top of my carb looks like. The choke is now operated via the cable that is shown in the photo. On mine the fast idle cam was secured to the body of the carb with the original screw AND a lock washer so it didn't move. There fore when you pulled out the choke lever nothing happened to the throttle mechanism. There is a separate throttle control cable in the cab but at this point it's frozen to its metal wound casing. At this point the engine is running and I can control the choke with the cable inside the cab. I have it up for sale and someone is coming to look at it tonight. If he buys it I'll let him know about what, as Jerry says, is a mixmaster (or Frankencarb).
