Start with the basics.

- Is the firing order correcty wired?
- Are all the plug wires in good order(terminals properly attached)?
- Proper point dwell/module air gap?
- Distributor primary wire(the small wire from the points or module) to the negative terminal on the coil?
- Primary connections clean and tight?
- Initial ignition advance properly set?
- All vacuum lines connected to their proper locations?

You always want to check the things that don't cost money before you start throwing money at the problem.

There are methods for checking the surity of the coil, condensor, and plug wires. I really doubt you'll find your problem with those as faulty.

As to the timing, I suggest that you may be setting timing to what seems right but is, in reality, very far off. Depending on what style balancer you're using, the timing mark could have slipped on the inertia ring and you could be looking at a bogus reference. You can get a good idea if you're in the ballpark by connecting a vacuum gauge to the intake. With the vacuum advance/retard lines disconneted from the distributor, you should see around 18" hg on the gauge. Very low readings at 12" or so indicate very late timing. Obviously, the vacuum method can't be used to determine what your timing is, but it can be used as a diagnostic tool.

There are other, more complex, things that could cause this but please do go with the simple things first.
