The title says it all. Having issues with my cold starts (throttle plates not closing all the way on start-up and not coordinating with fast idle cams). And not opening all the way when fully warmed up. Can this be solve easily by replacing the spring in the auto choke or is it more involved...

Woohoo! I got it working! It was the voltage regulator -- the inner most and outer most coils needed adjusting. The outer coil was not closing at all and the inner most needed adjustment for greater output. Thanks for your help guys. And now a more specific question, What voltage do these...

The generator on my 55 T-bird is not charging (6V ground-negative). If I disconnect the battery while the engine is running, the engine dies. My batt in the morning (fresh off of the charger) reads 6.6 volts. With the engine running, it reads 6.3-6.4 volts. I have polarized the generator...

Wow! All I can say is... YOU GUYS ARE EXTREMELY HELPFUL! I can't thank you enough. I have some work to do in making sure I have the correct and matched equipment on my car.

Just an update on this. I decided to do some more testing to see if I was getting full vacuum on the advance port. I did this by hooking up a transparent vacuum line to the port, putting the car in reverse (assistant in the driver seat, blocks behind wheels, etc) and having my assistant apply...

Also, you brought up a good point Sal -- the possibility of the rebuilder putting the plastic ball in there and it getting stuck when no plastic ball is needed in this model. I guess the only way I am going to find that out is by drilling out that stripped out brass port screw.

Think I am making some progress (hoping so anyway). About how far should it advance under light load in reverse approx? I have the timing dialed in at about 10 degrees advanced, and when I have my assistant give it some gas, I can see the timing mark move toward me about 5 degrees...

Sal - it is list 1078, so no ball! Fantastic. Do you think the rebuild place would have forgotten to clean the channel behind the check valve? I think I am almost ready to just reinstall it and see how she fares. Have you ever seen that passage behind the brass screw get totally clogged...

Wow- looks like you were typing while I was typing Sal and we cross-posted! Thanks very much for the incredibly helpful and detailed reply! Fantastic info. I will check on the things you suggested (starting with carb model number to determine if check ball is there in the first place). I am...

I am very much looking forward to his input and greatly appreciate your tip of the hat. Not many folks around anymore that really understand these carbs and their different iterations. One more pertinent detail -- this is an automatic. Here is a pic of the underside of the carb where you can...

So I have been trying to troubleshoot the no-vacuum issue at the vacuum advance port on my carburetor. I am able to blow air through the port and into the venturi just fine, however, when I have the carb hooked up and running, and put the engine under load, I am not getting ANY vacuum or suction...
