Blue smoke indicates unburned fuel.  If the engine runs well otherwise
(doesn't miss, cough, etc.) and the ignition tune-up didn't help much,
your problem sounds like a fuel system leak.

If I intrepret your description correctly, the engine was difficult to start
esp. when warm and put out blue smoke when the engine did finally start.
A fuel leak into the engine will flood the engine making for difficult
starting.  If the engine has a chance to cool down, the fuel that leaked into
the engine will also have had time to evaporate and/or leak into the crankcase
(and dilute the oil - you can sometimes verify this, especially if the car 
has been driven only for short runs, by smelling the oil on the end of the 
dipstick.  If it smells strongly of unburned fuel - Bingo!).

I doubt that the condenser would have anything to do with the problem - its
main function is to prevent excessive point arc'ing and therefore increase
point life.

The age of the car (8 yrs.) indicates that it probably is due for a carb
rebuild.  Unless you have successfully rebuilt a carb before, I suggest 
that you buy a rebuilt carb from a reliable auto parts place and install
it yourself.  There are other wear out mechanisms besides gaskets which 
rebuild kits don't address, not the least of which is throttle and throttle 
body wear.  *GOOD* rebuilt carbs are screened for excessive wear as they
are rebuilt, and therefore, on high mileage cars are the way to go.

					Good Luck!
