I remember when I bought my 924 they said the smog tech had to retard the timing or something to get the car to pass smog, so how do I adjust the timing to where it should be? thanks!

To adjust the timing correctly you will need a stroboscope lamp, which is a tool that you can buy at any auto parts store. Since these lamps cost about $40-80, it might be a good idea to leave the job to a mechanic who already has the tool. To get the correct setting you must also find out what the correct timing value is for your car (usually stated on a sticker in the engine bay or in the owner's manual). Here you can also see if the value is to be set with the ignition vacuum hose connected or disconnected.

There is a relationship between the octane of the fuel and the advance of the spark timing. The real answer is: as advanced as possible without causing the engine to "ping." The higher the octane the greater the advance.
Racing cars burning 105 octane fuel will be in the 20+ range. Gasoline Drier (methanol) is an inexpensive octane boost.
I knew this old time country mechanic that would time an engine by setting the distributor and accellerate up a hill. He would continue to advance the engine until it would ping. Then adjust it back 1 degree. None of his customers ever complained.

I have found that the early (77.5 pre's) distributor have the far best advance. Place one of those on your car to get some extra high end power.

Also- I have found that advancing the timing should be done carefully. You can easily advance it too much! This was proven on a dyno readout! Please take caution to this!
