Slant six idles rough

Shaun65dart said

Hey guys. 65 dart 225 slant 6 automatic on floor. Stock carrier single barrel, Petronix ignition. New plugs and wires. The engine runs well cruising rpms but at idle, it’s shaky. Compression is 130 all cylinders basically. I noticed air bubbles in the fuel filter. Could this be my cause for the shaky idle and if so, how would air bubbles even get in there?

Forget about the air bubbles in the filter that is a non-issue as regards your idle.
Is this fully warmed up at, at least 180* coolant temperature?
Is the carb correct for the year of the engine?
Does it have a PCV?
Is the choke fully off?
Does the car have power brakes?
Are there any other vacuum lines, other than the one to the distributor?
Is the exhaust stinky, as in burn-your-eyes stinky?

What happens when you turn the Idle-mixture screw in all the way?
What happens when you shift from Park to drive?
