Did you ever figure this out? Did replacing the diaphragm in the t-case have any affect on the idle? I'm curious as my '63 is the same way, no matter what I do, it needs the choke pulled halfway to idle...if I'm on the freeway, I can close it (I guess I mean open it...you know what I mean), but that's about it.

I'm not sure if this would make a difference or not. It depends if the vacuum switch on the firewall allows the the hose without a vacuum to vent or not. I don't think it does. If it doesn't and the seal where the shaft attached to the diaphragm the goes into the transfer case is good then there is no place for a leak since the housing is sealed. If it dies vent then it would cause a vacuum leak.
