This is his 350, not the 455. Looking back at his threads, he was talking about trying the 212. If so, 14" of vacuum is pretty good.
Make sure the choke vacuum pull off is properly adjusted and working also. This can cause a cold start to produce an over rich condition.
It is the 350 in the suncoupe. It’s between 13-14 of vacuum so that’s good. I kind of fell victim to listening to others and not myself. Everyone said valve stem seals but my gut said no. Lol.
