Guest Commodore Posted April 10, 2014 Share Posted April 10, 2014 First off do you have the stock carburetor. Link to comment Share on other sites More sharing options...

Guest Commodore Posted April 12, 2014 Share Posted April 12, 2014 This is a photo of a 1969 Firebird downshift switch. Does it look like yours? Link to comment Share on other sites More sharing options...
Guest Restorer Ray Posted April 12, 2014 Share Posted April 12, 2014 (edited) No, I will post a photo or two of the problem area on Monday morning. Again, i appreciate the response. Edited April 14, 2014 by Restorer Ray (see edit history) Link to comment Share on other sites More sharing options...
Guest Restorer Ray Posted April 14, 2014 Share Posted April 14, 2014 I added the photos to the previous reply by mistake. I'm new at threading. I hope you can see the area well enough. I think there is supposed to be some sort of bushing to go from the square drive on the switch to the round hole on the carb linkage. The large "watch spring" wraps around that and hooks to some sort of lever that is also missing. Reading the service manual, this is all for adjusting when the trans kicks down. Let me know if you need anything else or would like to contact me directly. Ray Link to comment Share on other sites More sharing options...
Guest Commodore Posted April 15, 2014 Share Posted April 15, 2014 The only photo I could find was this one of a 1967 Cadillac. Not good enough to help I think. Link to comment Share on other sites More sharing options...
Guest Commodore Posted April 16, 2014 Share Posted April 16, 2014 I have found some more information from a Cadillac forum. "You're missing the metal "finger" and spring that attaches to the square tab. The throttle bracket on the carb pushes the finger back, thus rotating the square tab which activates the switch. Was only used on 68-69 models". Link to comment Share on other sites More sharing options...
Guest Restorer Ray Posted April 21, 2014 Share Posted April 21, 2014 Your photo is a step in the right direction. The '67 is very similar to the '69 setup. #1 is the downshift switch, #2 & #3 are the wires to the trans, and #4 slows throttle return rate, I believe. I still need details of the lever and how it's square hole is "clocked" on the lever, the bushing that might go in the carb linkage, and how the watch spring is placed. Can you tell me the name of the Cadillac Forum? Link to comment Share on other sites More sharing options...
Guest Commodore Posted April 21, 2014 Share Posted April 21, 2014 OK here is a parts diagram showing the carb linkage. It has been mentioned that the Eldorado has different part number and it is flat not bent. Here is link to the Cadillac and LaSalle Club forms.http://forums.cadillaclasalleclub.org/ Link to comment Share on other sites More sharing options...
Guest Restorer Ray Posted April 24, 2014 Share Posted April 24, 2014 Thanks Commodore, That diagram was the key. Your help was much appreciated. Ray Link to comment Share on other sites More sharing options...
