Slant 6- Idle and Running

no, warm motor will cause choke to pull off that step once you tap the gas pedal...its spring cocked like a gun...
Since I can now make changes with the car on, any change to the fast idle screw seems to cause it to stall, and by that token, any manual change to the choke causes it to stall. I'm still getting strong fuel odor.To be clear then, I am setting the fast idle cam with a cold motor and the engine off? Since the choke would be fully open and it's meant to no longer be sitting on the fast idle screw?

Made sure the mixture screw passage is clear, it is.

Was going to do valves today but didn't realize there wasn't a crankshaft bolt to turn, then I decided I would take out the spark plugs and do it by hand, and realized it wasn't a 5/8 plug. Can't catch a break ha! Will get there eventually.

I'm thinking more and more it is the carb. When warm, the car will start and run great IF I manually hold the choke closed a little, or a lot. With the car on I played a lot with the fast idle screw to see if I can create a situation where it would idle without holding the choke shut, I couldn't. Also, the regular idle screw is almost completely screwed in, otherwise the rpms are too low to keep it running. I've tried adjusting idle mixture, again this really doesn't change much.
