Does it die because you give it gas? I would try the double pump... It's what I have to do. From a dead stop I give it a quick throttle tap, let go, then give it gas. If I just give it gas right away, it bogs down and stalls out.
I've checked for vacuum leaks, a faulty accelerator pump, proper idle/fuel settings and nothing has fixed it. I'm thinking about a rebuild but the PO mentioned he had already performed one.
