Hi,
I hope you are feeling better. I looked at the pics and listened to the videos. I think I spotted two potential vacuum leaks. See pics below. The pics are from the video.
Next, at the very end, it sounds like the engine RPMs raised and it sounded like a misfire. Have the plugs been checked along with wires, distributor cap, rotor, and so on? What is the idle speed (RPMs)?
Next, the misfire or rough idle is almost rhythmic. When it happens, I hear a rattle. Could that be coming from the catalytic converter?
Also, if the engine was at operating temperature, I would think the choke would have opened more. That can be causing a rich fuel mixture.
Let me know.
Joe
