Brought Dart to shop to fix idling issue and car runs like s**t!

I have been chasing a slight idle roughness and burble under 2000 rpm for a few years now . Checked for vacuum leak , tried several carbs and 1000 different jet / air bleed / timing combos . I decided to try new intake gaskets and bought a set of Edelbrock embossed intake gasket and some Gasgecinch.

Smooth as a babies butt now !
