Hello all,
I recently purchased a 73 Dart, and it wasn't running right. I rebuilt the carb, which seemed very clean inside, being sure to blow out every passage with carb cleaner. I stretched the accelerator pump spring to make sure it had a good strong push. My issue is that something seems to be intermittently obstructing the accelerator pump outlet. It pulls back fine, and then you open the throttle/ release the pump and it absolutely crawls back in. And its not the spring. It goes so slow I have time to press on the pump and i cant even push it in faster. Oddly though, this issue seems heat related. When stone cold, I usually get a few pumps before it locks back up again. Any suggestions?

Thanks

Well I fixed my own problem but rather than deleting this I’ll leave a remark for anyone else with this issue. It was probably debris of some kind. I sprayed carb cleaner in the two holes in the throat as described by Dan on various threads. And that didn’t make much difference (though I feel it was important to get the cleaner in there). So then out of frustration I tried just beating the top of the carb with a wrench and surprisingly enough that worked. Everything is freed up and the accelerator pump is pumping as it should.

Thanks for sharing "what worked". As the psychiatrists say, that gives us "closure". And on this site, many of us need psychiatric help!
