In the (relatively) near future I hope to video of the action of the manual choke. Its relationship to the dash lever is not exactly linear. That's what all that linkage is about. Will post.

Are you using the manual choke kit from the mod? You have a EE-15 carb?
Looking at the drawing I think the choke shaft is turned by a coaxial spring to prevent excess force placed on the choke plates. Not sure how it is driven by floating lever. I think there is a spring that pulls on the choke cable so it doesn't kink when the cables is pushed by the control lever.
I think the design may be like this one.

This is controlled by a flexible cable that connects to the choke lever in the Quad housing?
Are these kits still available? I assume they cost more than $3.95 listed in the bulletin.

As one can see, the linkage is far more complicated than a simple replacement of the automatic choke by a lever. The major difference is that the design of the choke butterfly makes it necessary for the choke cable on the supercharged cars to pull forward, so the choke cable has to come forward of the carb then back to the linkage. On the EE?15 the cable runs directly to the linkage.
Can't get at my car right now, but I will try to post a photograph of my manual choke in the near future.

It would be nice to have this and other manuals on a searchable disk like the newsletter.

My automatic choke was removed and it was converted to a manual choke. My choke lever and idle screw look like they were hand made.

I would like to see a photo of the original automatic choke carb and one that was modified to manual choke.
My question about chokes started this thread was not fully answered. Is the manual or automatic choke car more drivable?
The following thread has the statement "A manual choke is preferred as the Cord intake manifold heats up very slowly. "

My car, with manual choke, is put away for the winter but I can uncover it and you can have a look. I'm in downtown Toronto. Give me a shout if you're coming down this way.

Re:
On these cars the Choke lever on the dash is only there for good looks.
I am struck by the thought of some guy whose Cord won't start on the first try who then starts manipulating the choke lever, not knowing that it is not connected to anything. When the engine DOES eventually start, he thanks his car-Muse for the designer's forethought in providing a manual choke.
Pay no attention to that man behind the curtain!!
I can't stop giggling over this. <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: -->

To answer your question on the Choke - I think (someone will correct me if I'm wrong) the early cars had an electric choke on the EE15 carb. The wire ran directly to the electric choke and as the bi-matelac strip warmed up it opened up the choke. I have this set-up on my car and it has worked very well for 20 years. On these cars the Choke lever on the dash is only there for good looks.
On later cars the electric choke was removed and replaced with linkage to the lever on the dash - a manual choke. Most of the cars today have the manual choke.
The gas lever is a throttle linkage to the carb. You can use it as a fast idle if you are sitting still or as an early cruise control.
I hope that answers your questions (and probably gives you a few more).

I hope someone can help me understand a bit more about dash controls for the carb. I have not yet bought a car, so I can't just go and look. From the Stromberg data sheet for the carb I see that the choke is automatic. There is a bi-metal spring and an electric heater to remove choke function once the engine is warm. Some questions...
What is the "choke" switch on the dash for? The electrical diagram that I have been using does not suggest a switch between the generator and the choke.
The dash has four switches marked "Lights", "Gas", "Choke" and "Inst". Is the gas switch for some sort of fast idle? Again the data sheet doesn't suggest anything but automatic fast idle.
Any help understanding all this is appreciated. BTW if anyone needs Stromberg EE-15 or AA-25 data, send me your Email and I will forward them.
Cheers,
Tom Hussey
