I rebuilt the carb, and the car began to run properly with still a few warming up issues due to the car not running in months. Within a day or two, i am experiencing very similar problems i had before the rebuilt. The car would would begin to die out every time i slowed down, and when it would come to a complete stop, it would be definitely die out.

Could this be due to possible vacuum leaks as said before? I have replaced many of the lines already. Any last suggestions would be great, and thank you to anyone that has already given their inputs.

 

i didnt read the whole thred. matbe the brake booster has a hole in it? pull the hose plug it... drive it be carefull cuz your brakes will be hard to push. and see it the booster is bad. or you can use a vacumm pump on the booster if you have one.

 

After tweaking with the idle and gas mixture screws, the dart seems to be doing much better. It takes a little while to warm up, but stays running once warm. Thanks a lot for all your inputs; it's nice to have a car i can drive again!
