Slant six idles rough

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?
