Timing = 18 degrees at 1100 RPM
Idle in drive = 550
Idle in park = 900
Idle with A/C = 650
Set the timing with the vacuum advance disconnected. Reconnect the vacuum advance and set the idle screw to the optimal idle. I have never really been able to achieve smooth idle at 550. My car idles more smooth at 750....that puts my idle in park about 1000.
You can then trim out the fuel mixture by using a vacuum gage and adjusting the idle mixture screws to make it run more rich or more lean. Good rule of thum...run the screws all the way in, turn them about 2 turns out and start the adjustment from there. In is more lean - out is more rich. Hook a vacuum gage up to a manifold vacuum port and read the gage. The idea is to adjust the mixture screws until you get the highest point of vacuum. Mine is about 19 - 19.5 at 750 idle
It is not about adjusting the screws to be exact (although they shouldn't be too far off) it is about fine tuning the fuel and air mixture. Take small 1/8 turns, rev the engine up, let the engine settle, watch the gage adjust some more, etc. You may need to readjust the idle during the process as well.
Take your time you'll get it.
