383 .484 purple cam. Put this on new out of box ran great sent car to body shop got it back after 2 years while putting the dart back together started it up let it run for a while ran good then one day would start or run. Opened it up and there was crap in the bowls so I clean it out good put a rebuild kit in it. When cold will start and idle then once it warms a little it dies. If I throttle it I can keep it running but instant I let off gas it just dies I throw my 625 Edelbrock on there and it's fine. I'm stumped taken the carb apart like 4 times nothing's plugged
