A general number for timing is around 10 but that can change based on the engine setup. The idle speed also depends on the set up but its about 900-1000 and 700-800 in gear with a stock engine.
The idle control valve works by regulating the idle speed of the engine. The idle speed of the engine is usually controlled by the engine of the computer.
Most late model engines have fixed (non adustable) timing and idle speed adjustments. If there is a problem with either, it's probably related to an input signal to your car's on board engine management computer.
There is a idle screw on the throttle linkage on the carb that you can turn to increase the idle speed and then hook up your timing light to check the timing.
Idle speed is normal.
of Idle
The idle speed control solenoid controls the idle of the engine when the air conditioning is engaged. Since the ac pump draws down the engine idle the solenoid increase the idle when the ac is on.
Idle speed is automaticaly controlled by the computer. If idle speed is not correct, the car has a vacuum leak or a sensor problem.
Most people set the timing at idle speed. Around 700-800 rpm. If you have an advance timing light, you can set it for total timing, which is all in by 2800-3000 rpm.
You may want to check for sticking throttle linkage/cable and also your ignition timing may be advanced
