Fabulous demonstration on mold making. I really like the way you made your air channels.

I'm having a devil of a time getting parts to pour correctly - I've tried making several molds, adding more air channels from the part to the large air channel depending on what area of the part is not forming, etc., clamping at bottom, top, middle, etc. using baby powder to prevent sticking, etc., and I cannot for the life of me get a decent pour! I'm out of ideas - I have taken pics of my mold, part non formed in the mold, etc. Do you have any time to answer some questions, or perhaps point out (based on my pics) anything you see that may be incorrect? Thank you

I'd be happy to help out. And look at any pictures you have.

my zinc is just pooling in the opening of the mold and not actually running into the mold itself - any help is appreciated

It sounds like the air in the mold is blocking the flow. You must give it a way out. That is why I always build the mold with an air channel. If you did make the air channel and strategic off cuts then it could also be that the zinc is not hot enough. I pour at about 800 degrees. It also flows better the second attempt because the mold is warmed up.
