plugs were all black, dry not wet. Is it too lean? Its a 750 dp. I have 76/79 jets in it right now. any suggestions?

Sounds like its too rich! Was this a WOT run? If you can't get to an exhaust analyzer, I'd try some smaller jets to begin with.

350, 750dp.
i always thought black and dry it was too lean, and when it was wet(with gas) to rich.
