tryin to break in new engine, ruff idle

A couple of things I noticed as I went through this thread:
1) Are your new wires copper? That is a no-no with a lot of electronic ignitions.
2) Is your fuel pump old. Older pump diaphragms are not meant for the new crap gas and disintegrate. You may be getting crap in your filter and impeding fuel flow.
3) Have you checked the coil? A lot of times coils will act up only after they are hot.
4) Gap on your dizzy .008?
5) Plugs gapped at .045? Electronic ignitions usually like a wider gap than normal.
