I have not driven it.

he water was solid rust color when I flushed it. I used a flush kit so I was putting water into the water pump/intake ports. I ran it, let it cool down, drained the radiator then repeated until the water came out clear. Thought it would not hurt to have the radiator hot tanked to be sure it is flowing well.

Water pump had some corrosion.

So did you take the radiator out to a shop to have it flow checked and rodded out?

Whenk you replaced the water pump, did you stick you finger or a coat hanger to see if you could get any more rust out.

Next is plugs, points, dwell adjustment, check intial advance, varify mechanical advance is working, varify vacuum advance is working.

Have you rebuilt the carb?

You have a timing light right?
