Check the counter weights under the module in the dist and make sure they move freely. If you have a vacuum gauge you can get the timing fairly close, adjust for the highest reading and back it off just a tad and you'll be in the ball park and you can do the same with the air/fuel mixture screws on the carb except you adjust for the highest steady reading. Old radiator hoses do have a tendency to collapse under pressure and heat and will restrict water flow.
