Does anyone have an illustration showing where this spring attaches? Also advice how to adjust choke pull down so as to have 5/32 opening on cold start. Problem I have is choke is closed at start. Any help especially photos or drawings most helpful.
Thanks
Charlie
 
Can you post pics of what your working on? Thermoquads have some slightly different setups over the years.

Choke is supposed to closed and then pull off as soon as it starts. Thermal spring takes care of the rest of the opening as the engine warms. Is your vacuum pull off working?

Thanks for your quick response and offer to help. Yes, vacuum pull off is working. Problem is at start the immediate pull doesn’t function, so no high speed idle and running way too rich.If I just nudge choke valve it opens, fast idle works and pull down works. Attached are a few pics,you’ll see that spring I’m talking about. Did a careful rebuild on it, but obviously I missed something.Thanks for your time,look forward to hearing from you. And to boot plugs foul quick due to prolonged full choke. Checked idle mix (good). Think maybe that spring not attached an issue.
Thinking maybe bend (shorten) choke pull off rod would do it.
If I knew of a local (Atlanta) Thermoquad guru would bring it to them, but no such luck. Just FYI car is 74 satellite Sebring Plus 400, 4spd. All original and I’m the original owner too boot!

You can bend the tang in post 4 to help and/or you can tweak the rod from the choke pull off a little. Your rebuild kit paper work should have had a measurement for how far the door should open when pull off is working. I’ve found I need a little more than what’s recommended. I’m also not running these are in the dead of winter either.

Thanks for your help, will work on it tomorrow. The door should be open 5/32, will use drill bit as guide.
 
Actually, on the Thermoquad, the choke pull-off doubles as a control for the rate of opening of the secondary air door. There is a specific adjustment of the rod length relating to the air door not the choke. How far the choke opens is adjusted by bending the tap with the slot. These adjustments need to be made in a specific order to ensure correct function of the choke and air door, check the FSM or instructions packaged with the carb kit for the correct adjustment procedure.

Understand the need for proper sequence,the instructions I have a little difficult for a novice like me to follow as they tend to be vague.
Followed the rebuild as shown on You Tube from “Rocky” in Canada, was great tutorial, but don’t recall much about adjustments. Will let you know how it goes.
Thanks again
Charlie

From an original Carter kit. If you can't make out any details, PM me an email address, I'll send full size versions of these directly.

Thanks for the detail will check what I have and adjust accordingly.
Had a little time today to work on it and something is not right. With your photo ( great shot) of the spring as a reference, my linkage seems different. I’ve attached a few photos. I don’t have that eyelet for the forward attachment. Take a look, this strange. Did different model have different linkage? Take a look, what do you think ?
 
Sorry hit the send button for uploading pictures here the are.

EXCELLENT explanation and advice, especially the rebuild kit adjustments.....verify with FSM. Take your time and as an additional consideration, verify that the choke coil auxiliary heating element and its control switch (thermostat) are functioning correctly as it effects the time (reduces) it takes to come off the choke completely and that the choke coil's innitial setting is correct, as noted in the FSM. Just my opinion of course.

After digging through my Thermoquads and parts, you likely have the early version of the later spring assembly. Without the eyelet, the spring would go into the slot pictured.

Thanks Bob. Thermoquads always a challenge, especially for a shade tree mechanic like me. I know just enough to get into real trouble, when finesse, patience, and addition to detail required. Sound like a cranky old man, hell that’s what I am !
