Every vehicle I own runs and starts on a mechanical pump with no help from electric pumps.
If your mechanical pump isn't getting the job done, it probably needs a rebuild. As bartamos said, pump the hell out of the carburetor while you're cranking the engine. Maybe your accelerator pump is weak.
What's the story on your mechanical pump? New? Original? Rebuilt recently? If it's a new pump, get rid of it and find a good used original pump to rebuild.
