Sheryl,
Does it have a dual connection vacuum advance? Have you sucked on the vacuum advance hose with the dizzy cap off to see if the advance plate moves and the diaphragm holds it?
First check the current timing and note it. If it not near 10 degrees BTDC spin the dizzy up to at least 10 degrees BTDC. If it has a dual connection vacuum advance I would replace it with a NAPA VC 970 single connection vacuum advance. If you do this you will definitely need to time it as the timing will change. Do note the current timing before you start.
The VC 970 is adjustable. We can talk about that later.
