It starts getting complicated when trying to control the injection pump, what may help with power may cause issues with the idle.

The vacuum controls the throttle using the venturi in the throttle body and a spring in the injection pump, less vacuum would make it richer, but this is not something I have dealt with, all my experience is with integrating a turbocharger into an inline injection pump.

Do you have cod-liver oil in the vent hose cavity of the injection pump or is it dry?

It may take a few weeks for a response as I do not have internet access right now, using Starbucks WIFI.
I know the voices are not real,
but they have some really good ideas.
