Fuel Delivery Issue; Holley 1920 Dies Immediately After Letting Off Gas

Does it idle any better by backing the idle mixture screw out? If it's an emissions 1920, I wouldn't be surprised if it wanted 2 or more turns out from being seated.

Additionally, do you have the correct base gasket? It should have a hole to feed a vacuum port in 1920s that the later gaskets don't have.
