Could you 'splain that a little further
Wrenchbender? I've learned that you can follow the vacuum line into the distributor and make a circle and that's the way it turns, but which way does it "point"? in or out?
Turning the distributor the same direction as the internals turn will retard the timing. You should be doing it with a timing light if you can get it running. Checking the timing is a good start, but if it only runs badly when warmed up you probably have a different problem, like a weak coil or bad condensor.
