Slant 6- Idle and Running

adjust idle speed on choke and off choke. 2000 RPM fast idle (choked) 750 (800 for 198 CID) hot idle. Yours is a type III choke setting: 2nd step in figure 5. Make sure choke pulls all the way off when warm too.

Ok thank you for that photo, that I have tried to do but I feel like there is a lot of play in where the fast idle cam sits on the idle screw. I will try to get a video to show what I mean, but it may well be normal. Am I doing this adjustment with the car running? I've been trying to set fast idle with the engine warmed but off and the throttle opened to 20 degrees, setting it onto that 2nd step.

With the car fully warmed up should it remain sitting on that 2nd step at idle? Because it doesn't. :( I can try doing this adjustment again with a running engine at least now though.
