To separate the idle cam from the choke
How about a small (they make them LOL) gearhead 12V motor connected to a replacement curb idle screw. So long as the motor electrics is isolated from ground (such as PM with two commutator wires) all you need is a momentary, center off, DPDT switch to reverse/ forward the motor, and screw the curb idle in/ out

Believe me, I have considered this route but did want to go to all the expense details to add another electric device and over complicate this.
How about a curb idle kicker like what came on my manual trans 1970 340.
That was my first thought, but one position only isn't worth it to me to do.
Along that line, how about an AC idle compensator kicker rigged up so you control it?
Same answer as I gave AJ.:D
Google vernier control cables. It is almost exactly what you describe. Can rotate knob to adjust throttle. The ones i sold in the past had approx 1” diameter knob.used with a bead chain, it wont affect normal operation.
my 68 chevy had a manual choke, pull it out and start it, and then i could keep idle up with choke off. If i wanted fast idle,i could feel the steps in the pedal. Was the only manual choke vehicle that would work like that,most didnt work as well.
all the aftermarket choke kits are junk, especially the cable control.
The manual choke route is actually closest to what I want to do, but I'm kind of a "One off" type.
Just a simple twist knob to raise or lower the idle without involving the choke or I'm not going to bother.
Somebody has to ask so it will be me. Why? Why do you need fast idle when the engine is warm? I am with Kowalski. A a/c solenoid hooked up to a toggle switch would do the trick. Not adjustable though. Hook a cable up to the fast idle cam.
I don't "need" it, but it might be something to do while it rains for days like the weather report says.
I'd like my idle a little higher some times but not others.
Pretty sure I have made a decision, but I'm going to check the links Tooljunkie posted just in case.
Probably will end up using a cable like a choke kit uses, but I want the adjustment to be finer increments than just the push/pull like a a choke.
AND in doing this I want to get rid of the steps in the idle cam and make it a smooth transition so I don't have to touch the throttle at all to adjust.
I know, everyone should have such big problems. :D
