An A/C compressor takes about 6 horsepower to turn it and when an engine is idleing, it is producing about 30 hp so when you take away 6 hp from 30, it puts quite a load on it. There is also a device which increases the idle speed when the A/C is switched on. If this is not working or the idle is set too low then rough idle may occur.
Use a dwell meter to adjust the points to 30 degrees dwell.
Stock rebuild- it has been said that 10psi per 1000 rpm. At idle 20-30 is about right once the engine is warmed up. Of course this will also vary with the weight of the oil used-not much but it will
