I drive a 250 Chevy w/500cfm Edelbrock, it runs and idles great. But sometimes after it's warmed up (maybe 20 minutes)it will stall at a "quick" stop. Then it needs to sit briefly and then full pedal until it finely restarts, then she runs fine again. My machinist suggested maybe a Dash Pot.

Anybody have experience with these and which one or type is recommended?

Other suggestions?
