Yes. All above are correct. But.... If wild choke settings for lean and rich don’t help And all secondary spark possibilities are eliminated - this sounds to me (vibration meaning one or two holes) like one or two cyls have very different requirements for cold start mixture from all others. This would indicate lean (vacuum leak) at manifold near the dead holes cold or very different compression on one or two compared to the rest. Good luck. Keep us posted on the root cause. Hope she was not sold for this issue. Someone else chased and could not rectify this?
