high Idle 318

Im confused...

How the choke / fast idle linkage is supposed to work.

1. the thermostat (heat riser) pushes up on the choke lever on the pass side of the carb when the engine is cold.
2. the choke closes
3.the choke rod pulls up on the weighted fast idle cam.
4. before you start the car your press the gas pedal down this allows the weighted fast idle cam to rotate counterclockwise.
5. when you release the pedal the fast idle screw comes to rest on the fast idle cam increasing the amount the butterfly is open
6. after the engine starts and heats up the choke thermostat ( heat riser) pulls the choke lever down and the choke opens.
7. when the choke opens it rotates clockwise allowing the weighted fast idle cam to fall by gravity out of the way.
8. the normal idle speed screw takes over and the car runs and normal slow idle.
