Sounds like the normal lack of initial timing scenario.
Did you set your initial with the vac line to the dizzy plugged?
If so bump it up to 14 degrees. If it gets better then try a couple more degrees at a time until it's hard to start when hot or it pings.
Make sure you turn your idle speed down as low as possible when you set your timing.
