Rough idle after rebuilding carb

Hello all,

I have a 1949 Packard with a 327. I recently rebuilt the carb and now after it warms up, it idles really rough (to the point of quitting). When driving, it seems to run fine. It is just at idle after warming up. I have adjusted the low idle jets with a vacuum gauge attached and I think it should be close there. I was wondering if it could be the metering rods. Unfortunately, I did not mark where those were originally set when I took it apart. Any suggestions would be greatly appreciated. Thanks.

Also, the carb is a Carter WGD.
